Deleted repository still takes up space in Usage Quotas / Storage

We deleted a repository to reduce the space it was taking up but it is still taking up space when viewing our groups usage quotas/storage tab. The repository now has a name of “(original repository name)-deleted-(numbers)” and when clicking on it a 404 page appears. Is there a way to permanently remove this so our storage space gets reduced, do we have to wait a specified amount of time for it to be removed ?

It got completely removed after about 5 days.
