how to delete orphaned link and upload file after gc?

[microyahoo]

I use harbor as registory for testing. I cleanup harbor after test finished, then run registry garbage-collect cmd/registry/config-harbor.yml -m to cleanup residual data in s3 bucket.
But I found that even after executing gc, there is still a lot of residual data, mainly the link files of layers. How can I clear this data?

[root@cicd-node01 ~]# rclone ls test-harbor:test-harbor/docker/registry/v2/
