After renaming folder in pictures old name remains?

[jum]

I have just turned on the picture viewer in my DX, and this works kinda (I see partial updates, like the other folks on 2.3). But I did rename the folder I created in the pictures folder and now I have two books on the home page, one with the old name and one with the new name, both referring to the same pictures. I did look in the pictures folder, nothing duplicate there. Where is that info stored? It must have cached the pictures as well, as these are displayed with the old name as well.
