/storage/docker/registry/v2/repository has not been deleted when gc & purge policy

[Jim0530]

If you are reporting a problem, please make sure the following information are provided:

Expected behavior and actual behavior:

I have configured a policy for every project to retain artifacts pushed within the last 3 days, with tags matching **, including untagged artifacts. However, the storage is still full. Upon inspecting the /storage folder, I found that while the /storage/docker/registry/v2/blob directory is being correctly purged, both ui and the result of du -h blobs are equal.
The /storage/docker/registry/v2/repository directory still contains data from repositories that have already been deleted and no longer appear in the UI.

Steps to reproduce the problem:

Versions:
Harbor ==> v2.12.0-9da38ae0
