Impossible to remove items from a folder
Issue
You cannot remove one or several items from a folder, even though you have the necessary rights.
Fix
Check that the Display items from the subfolders option is not activated. If this is the case, all items stored in the subfolders are displayed. This view prevents subfolder items to be removed.
Deactivate this option, select the appropriate items and click on the More icon. The Remove from folder option should then be available.
