It's nevertheless answered in the FAQ, under the entry named "
Bags"...
Regarding the bag options I have no idea, they may be opening off screen, try to rename your uisettings.ini and start with a clean UI (without loading an alt's setup) to see if that fixes it.
PS: You can also put in a script via the ControlCenter, but I currently do not have any UI files at hand and therefore can't give you the exact code.
