Awesome, thanks for your reply. I can kinda see what i was missing, do you have a later version of the editor? In my version 1.0.2 the candidate league only allows for a true/false value even though it says UID, thought that might have been the issue.
I have a custom version I'm testing for Archi, that fix is coming in the next release, I can share it with you via PM if you need it and can't wait.
