Repository "Files" Size is Large than Expected

I recently used git filter-repo on a repository due to discovering sensitive data in an old commit. After applying the change I noticed the repo has gone from “900 KB Files”, to “63.4 MB Files”, does anyone know why that might be the case?

I’m using the public instance of GitLab.

The repository where the issue occurs is here:

May I just get advice on why it’s like suddenly become so large, and how I could address it?
