It's not a bug, you are probably using the latest UI, try to use another heroes.db3 that have older UI.
@WAMVN, you still have Vindictusworld client? Can you do a quick test on their server?try to test their avatar shop if have any transaction failed error. Ive asked players there, they said work fine but I don't know if he\she is telling me the avatar shop or beauty shop.
