Unable to delete

I get storage warning so I go into the asset manager or whatever its called and start to delete all my old files. To my utter surprise, after I am done my storage space used actually goes up. I have, as near as I can tell only a small number of assets left and cannot for the life of me figure out what on earth Adobe has done to take up the extra space. This is exactly why I will never let Adobe manage my assets in the cloud or use anything but Lightroom Classic.
