Im completely new to Node-Red and have no clue about coding and that’s the main reason I started with nodered, because it seems like I can learn it.  
Here is my setup  
NodeRed is running on RPi3 Raspbian with desktop 4.14, 8 gpio pins connected to 8 channel relay powered independently with 5v power supply.  
Added nodes:  
Node-red-contrib-gpio  
Node-red-contrib-ui  
Also added and later removed (thinking that was the cause of the problem) nodes:  
Node-red-contrib-ui\_j  
Node-red-dashboard

I’m utilzing 2 nodes to control relays and delay node for “soft” start  
UI node switch and rpi gpio  
Each gpio has its own ui-switch and I can control them from UI web interface.

Here is the problem  
I added one more “Master” switch and wired it to control all 8 switches with delay node in between.  
It shows up in UI and I can control it from there, but if I switch On/Off one of the switches and then click on Master switch it would activate all switches except the one that was active recently.

Will add snap shots as soon as figure out how to do it

Not related to your question but you should start by removing  
Node-red-contrib-ui and Node-red-contrib-ui\_j  
and after restarting Node-RED then install Node-red-dashboard

node-red-contrib-ui was redeveloped into node-red-dashboard several years ago.

Which also suggests you are using an old version. What version of Node-RED and nodejs are you using?

Node-red v0.19.4  
Node.js v8.11.1  
Dashboard 2.13.2

I did as you recommended, imported the flow I saved and now I get grey screen on UI

So you have uninstalled all the dashboard nodes apart from node-RED dashboard?  
None appear on the list of nodes on the left hand side?

If so, what do the logs say on startup?

Great at least now you are on a version of the dashboard that is being developed and supported.
