Cannot Permanently delete files from Deleted folder

Same issue and I opened a ticket. Crazy thing is if I am able to delete some of them, next time it syncs it puts them right back. There was an earlier thread on this problem, looks like going back to 2014. Back then support would delete for you if you opened a ticket, but seriously why is this problem not fixed yet?

I wonder why they can't be deleted unless they're being used by something else for which you don't have the right permissions to access.

if you have an enterprise or teams plan, the admin should delete them.
