Storage usage questions

I have NC 22.2.3 running in a SNAP on Ubuntu 20.04.3 with an external 5TB HDD set as my default storage space. I have users quota set to unlimited but with one user, with 814GB of storage used, it says that there is 96% of the storage consumed. For the life of me I cannot figure out how to solve this. I have run the nextcloud OCC to clean up the trashbin and the other commands but still have the same problem.

Any help would be greatly appreciated.
