1) Get latest ULX from Github. Yours is several months out of date.
2) Your groups inheritance and can_target are a mess.
Though you CAN have custom groups, the more you have, the more things get confusing.
You've got branches in the inheritance tree all over the place. Possible, but only if you know what you're doing (and apparently you or your staff that made all the group inheritance don't)
The biggest issue I see besides many confusing and mixed case groups inheritance tree is that you seem to have can_target set to NOT target those below some others, or inherit groups above that can't target below.
If you clean up all your fancy group names, and clean up the tree so it flows down top to bottom better, I think your issue would clear itself.
