Sometimes a patch will mess with keybinds. I noticed that all of the Blizzard bags were opening with AdiBags as well. So, I went to the keybindings interface and noticed that B was bound to "Open All Bags" rather than where I had it before, "Toggle Backpack". This is the binding that you should be using for bag replacement addons. All of you should check your keybinds.
(Also, I was not aware that Bartender took care of opening your bags for you.
