Hello! I'm not sure I understand what you mean by default shelves, or the bigger squares.

If by default shelves you mean the dropzones, they're not shelves, they're a basegame thing. The whole point of Shelves is to drag cards automatically (or when you press TAB, depends on the settings you set) into the proper shelves. Dropzones won't keep their cards if you put some back there. The only exception is if:
- you never hit TAB again (it's a "force organize" action in a way)
- enable the auto-organize in Shelves settings

In theory, if you move a card manually, Shelves remembers that and then never tries to move it automatically again. But if you hit TAB, it will re-organize everything again (IIRC).

If by bigger squares you mean the verbs, they're not handled at all by shelves. They're completely ignored.

I meant the dropzones my bad! The issue was recently fixed after a small update though so not sure what was going on but all is sorted!

Love the mod btw, I have pretty bad OCD and this helps so much <3

Glad to hear that!
