Hey @CI Backup, welcome to our Community!
Keep in mind, that deleted files don't use up your quota, so, permanently deleting them makes no difference.
Also, just to clarify, do you use our website when trying to delete your content, is that correct?
I'm simply asking, because you should be able to empty your device's trash, provided that you're using our desktop app, of course.
I hope this helps!
