Error When Trying to Use Field Security

I created a checkbox in developer mode and tied it to quotedtl.checkbox18.  I then tried going into Field Security Maintanence to limit access to checkbox18.  If I save and exit out of Epicor, when I log back in Field Security Maintanence changes are gone.  If I save and then hit fresh in Field Security Maintanence, I get the following error:


"FileName is neither a DataColumn nor a DataRelation for table FileSchema."


I also tested changing the security of a random field in a different table, and I got the same error when I clicked refresh.  Anyone know how to resolve this?  I can make a quick video of the issue and send a link if this doesn't make sense.
