When a release is done the changelog is created from the release labels attacked to the issues. However when an issue is backported to an older release the new release label is still attached. For example when an issue is fixed in main the release/26.1.0 is attached, however when this issue is backported it will also receive the release/26.0.1 lablel.

This means that when a release is done for release/26.0.1 the issue is added to the changelog for that release. Then when the 26.1.0 release is done it will include the same issue in the changelog again. This is counterintuitive and should not be happening.
