>             Project: Apache Ozone
>          Issue Type: Bug
>    Affects Versions: 2.1.0
>            Reporter: Wei-Chiu Chuang

> [~sarvekshayr] reported that after HDDS-13756 seems to cause a regression:
> https://github.com/apache/ozone/pull/9115#discussion_r2685116012
> {noformat}
> After this PR, observed an issue where usedBytes is high while usedNamespace is 0, even though the bucket has no keys.
> It appears that usedNamespace is being decremented incorrectly. In the overwrite case, the namespace seems to be reduced twice, whereas it should done once by 1.
> Since the bucket has no data, this likely indicates a problem in how namespace is being updated during the commit or delete flow.
