Problem with enforcement of disk quota limit

We host a large number of WordPress sites. All sites use the same package with a disk quota of 2Gb:

I had a customer install a backup plugin on WordPress which created a backup file of 34Gb in size.

Somehow, cyberpanel did not enforce this disk quota limit of 2Gb.

Yes, I confirm - package limits doesn’t work at all.
