How to Change Tag Version of a Release

I have an archive called “” that I am making available as a release. When I created the release I used “” as the Tag version, which was a mistake. Now when I try to edit the release my browser automatically tries to download the so-called ZIP file. I want to either delete the release or edit the Tag version, but I cannot access either option because the Edit option points to a URL that ends in “” and again tries to automatically download. I’m a new user, so apologies if the answer is obvious. Thanks for any help.

Deleting the release would be the easiest solution, but I can’t do that the normal way.
