Delete REMOVECOLLECTION=auto does not work with Folder Expansion

Hello,

deleting a file or folder within an extended folder does not work with "Delete REMOVECOLLECTION=auto", the delete button is grayed out. The same button also does not work via the context menu.

The command doesn't work in that context, which is why it's now disabled.
