Much of the information that appears to be deleted in Stager using the Delete button is actually just hidden and moved to the Trash can.
Because Stager is interconnected across different areas, removing certain items could break links elsewhere. To prevent this, deleted data is retained in the background but made invisible to users, it's 'soft-deleted'.
It can of course happen that something is accidentally deleted. In that case, you often can restore the information by clicking on the 'Restore' button next to the deleted data in Settings - Account - Trash can.
Note that not everything in Stager is soft deleted.
If an item is not connected to anything else, or if it can easily be recreated, it will be hard deleted instead. This means it is permanently removed and cannot be recovered.
