Is there any update to this problem?

So I tried everything and it didnt work, double checked it tried to make it simpler still didnt work, i removed the feat and re-added it still didnt work, other thing I noticed too is that when I check the box for "IS PROFICIENT" it resets back to not checked when i go back to edit it. 

So this is also happening to other feats with the same problem, these are even more simple and have the same problem.

Yes I created the feat and other feats similar to this that are having the same problem

First time making a thread sorry if I fudge it up. I keep getting that beautiful beholder ruined everything error when clicking on a homebrew Feat's Options Action to bring up the side bar for more detailed read on the action. My group kept running into this problem last night at our session. 

For example on this test character going to feats and clicking the action Swarm of Primahex you get the error. Is there any fix to this other than removing the entire homebrew feat?
