Repo size won't update after bfg repo cleaner

I ran bfg-repo-cleaner tool as explained in https://rtyley.github.io/bfg-repo-cleaner/ and apparently it worked. This tool removed files larger than 20MB that I uploaded to git repo by mistake.

The problem is that the git repo size in GitLab web interface still shows 250MB, when it should be <50MB.

I tried running the Housekeeping option and git gc in the server, but gitlab repo is still 250MB.

Any help?
