Hi,  
Using latest node red 1.1.2 with dashboard 2.23.0  
I'm using the multiple selection feature - i.e. inputting to the node a list of options (msg.options).  
Sometimes when I select one or more values - the msg.payload shows more options ??  
Also if I dont select anything - the msg.payload still shows one selection.

Here is a simple example which shows the bug:  
Try injecting different options, select some in ui and watch the output messages.

```auto
[{"id":"b5f025e7.bd0d58","type":"tab","label":"Flow 3","disabled":false,"info":""},{"id":"a8a952e6.7ea95","type":"inject","z":"b5f025e7.bd0d58","name":"","repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":195.5,"y":148,"wires":[["dbcf3065.9a563"]]},{"id":"dbcf3065.9a563","type":"function","z":"b5f025e7.bd0d58","name":"1,2,3","func":"msg.options=['1','2','3'];\nreturn msg;","outputs":1,"noerr":0,"initialize":"","finalize":"","x":385.5,"y":148,"wires":[["3c6d32ba.c9c93e"]]},{"id":"3c6d32ba.c9c93e","type":"ui_dropdown","z":"b5f025e7.bd0d58","name":"","label":"","tooltip":"","place":"Select option","group":"c64fd4cd.83f2d8","order":4,"width":0,"height":0,"passthru":false,"multiple":true,"options":[],"payload":"","topic":"update","x":537.5,"y":223,"wires":[["e7e69c60.403f5"]]},{"id":"e7e69c60.403f5","type":"debug","z":"b5f025e7.bd0d58","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","x":705.5,"y":220,"wires":[]},{"id":"7f3dd052.89ffb","type":"inject","z":"b5f025e7.bd0d58","name":"","repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":177.5,"y":243,"wires":[["e3037796.537d28"]]},{"id":"e3037796.537d28","type":"function","z":"b5f025e7.bd0d58","name":"4","func":"msg.options=['4'];\nreturn msg;","outputs":1,"noerr":0,"x":362,"y":240,"wires":[["3c6d32ba.c9c93e"]]},{"id":"abd6e2c0.37546","type":"inject","z":"b5f025e7.bd0d58","name":"","repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":163.5,"y":330,"wires":[["b55fe5c6.afd168"]]},{"id":"b55fe5c6.afd168","type":"function","z":"b5f025e7.bd0d58","name":"[]","func":"msg.options=[];\nreturn msg;","outputs":1,"noerr":0,"x":365,"y":326,"wires":[["3c6d32ba.c9c93e"]]},{"id":"c64fd4cd.83f2d8","type":"ui_group","z":"","name":"data1","tab":"e25f6f05.d09e6","order":1,"disp":true,"width":"8","collapse":false},{"id":"e25f6f05.d09e6","type":"ui_tab","z":"","name":"info","icon":"dashboard","order":1,"disabled":false,"hidden":false}]

Hi and welcome to the forum! You'll need to edit your message to format the flow file JSON properly. Otherwise it cannot be imported due to broken characters.

See: [How to share code or flow json](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506)

Using your flow, can you provide a step by step of how to cause the issue?

Select the first inject: 1,2,3. Select in UI 1 & 3 for example.  
Then inject the second option: 4. Select in UI 4  
Then inject the empty options.  
Inject again the 1,2,3 . In the UI , press the dropdown but dont select any value.  
msg.payload still shows an array of size 1 with one of the values

yes - def looks like a bug. When using multiple select it doesn't clear the "old" selected values if new options are sent.  
Well spotted. Thanks.

Hello,  
I've updated to the dashboard 2.23.1, which fixed the multiple selection bug (old history), but now I noticed a new bug...  
When you have values & labels (such as the simple flow shown below) - it outputs wrongly the labels instead of the values..

```auto
[{"id":"456c58b2.68d648","type":"ui_dropdown","z":"3a8437c5.8f2d38","name":"","label":"","tooltip":"","place":"Select option","group":"c64fd4cd.83f2d8","order":5,"width":0,"height":0,"passthru":false,"multiple":true,"options":[{"label":"zero","value":0,"type":"num"},{"label":"one","value":1,"type":"num"}],"payload":"","topic":"","x":240,"y":158,"wires":[["333fa5ae.b00bea"]]},{"id":"333fa5ae.b00bea","type":"debug","z":"3a8437c5.8f2d38","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","statusVal":"","statusType":"auto","x":479.5,"y":160,"wires":[]},{"id":"c64fd4cd.83f2d8","type":"ui_group","z":"","name":"data1","tab":"e25f6f05.d09e6","order":1,"disp":true,"width":"8","collapse":false},{"id":"e25f6f05.d09e6","type":"ui_tab","z":"","name":"info","icon":"dashboard","order":1,"disabled":false,"hidden":false}]

```
