Google Play: Can't RELEASE TO PRODUCTION because "a draft release in production already", what to do?

I am trying to release a new version of my app at Google Play Console.

I have one version which I didn't release and then I uploaded a new one to Beta that I want to release.

When I press on the "RELEASE TO PRODUCTION" button I get the following message:

"To release to production, ensure that you don't have a draft release in production already"

If I try to "RELEASE TO PRODUCTION" the former version I get the same message. How can I break this loop? any ideas?
