Remove releases in GitLab

I have a problem with my releases in GitLab.

I created them in my project with tags. Now I want to remove them, so I deleted the associated tags but my releases are always displayed. I searched on Google and Stack Overflow but I can't find any solutions.

How can I remove these releases without their tags?

What are releases in GitLab?

In GitLab, a release enables you to create a snapshot of your project for your users, including installation packages and release notes. You can create a GitLab release on any branch. Creating a release also creates a Git tag to mark the release point in the source code.

Does deleting a tag delete the release?

Summary. Releases always refer to a tag. When you delete a tag, the corresponding release is not deleted.

Go to Project Overview -> Releases
Click the release you want to delete
Scroll to the bottom. Find the tag icon. Click on the tag.
There is a trash can button for the tag. Deleting the tag will delete the release as well.
