I'll wait to see if maybe SticklyMan has an input, but here's what I did and know...
1. I skimmed the file.. Looked fine.
2. I loaded the file in my game and no issues.
3. I installed ULX on a dedicated test server on a separate system as my game client so that it would need to stream the data to the client when I clicked the bans tab, and it worked fine...
You could have a conflicting addon or something along those lines, but I really don't have any way of knowing.
