Cloudflare R2 Incosistent Bucket Size

Hello, so i’ve noticed an inconsistancy in bucket size after uploading a large object and removing it.
The AWS S3 API also doesn’t seem to see the extra large objects and on my NAS it also, isn’t the same size on disk vs remote.

Remote (R2):

The bucket size never lowered.
I have also validated that they are no dangling multipart uploads pending is there something else I should be looking for?

NOTE: this is Hyper Backup on the Synology NAS.

This is the source disk usage, i couldn’t put it in the same post
