Nostalrius Begins - Quality wow vanilla realm (1.12)

My dad and I recently started playing together, and found that we can only open our main bag. We find plenty of pouches for both of us but we can't seem to get any of them open. I was wondering if anyone was having this same issue or maybe someone just has a fix for it.

Thanks for the help

Edit: We've discovered that clicking on the other bags makes noise as if they're coming up, but we just can't see it. The F8 - F11 buttons don't even make sound. The button that works is B.

The original keybind for B only opens one bag. If you go into keybidning you can change so that B opens all bags, maybe that will help.

I had the same bag problem after obtaining a 14 slot quest bag.

A relog solved the problem, maybe that's what you need to do as well to get it working?
