I think it would probably be best to confirm that it is indeed a sizing/tabling issue before resizing and putting the same sig back up.
Since I don't think GMs are allowed to respond to account-specific questions over the forum (it violates our Privacy Policy), I'd recommend contacting a GM directly in-game. That's probably the most direct route to get to someone who can actually answer your question.
I'd bring up phone/chat support, but the people who run that are typically account service reps rather than actual moderators so they may not know how to help you directly without getting a supervisor on the line or redirecting you anyways.
Honestly, a PM function would solve a lot of problems. But, truth be told, I can't imagine how many absolutely useless PMs would be spammed to GM/Dev inboxes on a daily basis so it's really no surprise that they've held off on it.
