Parallel Unitid option not there in modbus flex getter node

In my old workflows, I used to be able to check an option for unitids in parallel in the Modbus-Flex-Getter node, however, I am not able to see that option any more. I have node.js version of 12.13. This works on my other laptop, but not on a new laptop.

maybe the tab where the option is in has changed ?
i now see it under the Queues Tab in the modbus-client config settings
