Steps to reproduce

1. Have Bag and/or Menu bars
2. Check hidden for either/both
3. Reload client or UI
4. Bars reappear, hidden is unchecked in options

Additional Notes

Other bar types seem unaffected by this
Occurs on both default bars and newly created bars

ok cool thanks, I'll fix this. I want to unify the settings between all the different modules, right now they're all somewhat independently configured, thus why it works on some but not others.

I was going to report this for the cast bar, it's exhibiting the same behaviour.

Is this still happening?

Is this still valid?

Yes, at least for the menu bar (I don't have bag bars). Set it to hidden, relog, it's back. Guessing the hidden state isn't saved to the profile.
