Hello. I am not entirely sure why this is happening as I for the most part use the same set up of addons for all of my characters. In game when I open up my guild bank for example it does say that it does its syncing process of all the tabs, so I know that it is working in that aspect. But I do not ever see if whether or not I have a particular item in the guild bank when I'm away from it and hover over an item in my bag, even if I know for sure there are the same item in the guild bank.
