if you equipped backpack by icon in backpcak inventory, it can only be unequipped by clicking unequip button in backpack inventory which can be opened by B keybind (default, you might need to change that to avoid conflicts). to use back slot you have to enable trinkets/curios integration in travelersbckpack config file

My wife and I have this issue on our personal server. It isn't a problem as we've found that running /tb access twice solves the issue.

We have to run it evertime we log in. Just wanted to share our work around.
