Release targeting wrong branch after deleting another release with the same tag but different branch

[KroneCorylus]

Description

Steps to reproduce:

1. In a repository with at least 2 branches one with some changes (in this example: main branch, test branch) create a release 1.0.0@test (1.0.0 tag name, test branch).
2. Delete the created release.
3. Create a new release with the same tag but in the correct branch 1.0.0@main

Expected behaviour:
    The last release and tag should show the changes/commits made on the branch main.
Observed behaviour:
    The release show the changes made on the test branch even when the release says is targeting the main branch and shows negative commits like this:

More Info:
the main branch has a empty readme file
the test branch has 2 commits changing the readme file
the tag 1.0.0 show the file with the changes made on test branch
if a click on the "-2 commits" the "Compare commits" screen shows no changes.

Maybe the reason is that you didn't delete the existing tag. You could delete the 1.0.0 Tag first and then create the new release with the correct branch.

I will try to make an enhancement to optimize this process.

Deleting the release do not delete the tag? Im going to try what you told me a report back. Thanks

Yes you are correct. If after deleting the release you manually delete the tag, the new release is created correctly. Maybe if you choose a existing tag the branch selector should be disabled ?

Yes. If a tag exists, the selector should be disabled. I will implement this function.
