Odd Bag Problem

[Dadditude]

I am currently using the 66%, 3-column vertical bags with Fetish Nightfall, and have applied all of the "stay-put" features to them, including getting rid of the minimumsize/maximumsize which you have left in, and it's working well, with one exception. The box that I have in my 4th shared bank slot not only keeps 'forgetting' its position, sliding to the right or left each time I log in, it also keeps 'forgetting' that I locked it, becoming unlocked each time I log in. At first, I thought it must be a corrupted uisettings file, so I deleted it and started from scratch, but the box window still slides and unlocks on its own.

Any idea what the problem might be? I am enclosing the bag file I am using so that you can see if it is something I did wrong.
