title: Gitlab - Project cannot be transferred, because tags are present in its container registry
body: <p><code>Project cannot be transferred, because tags are present in its container registry</code></p>
  
  <p>I am encountering the above error when I try to transfer my git repository to a group.</p>
  
  <p>I have checked in <code>Repository/Tags</code> but there are none. I have also checked in CI/CD tabs and there's nothing outstanding there either. So I'm wondering what tags is it referring to.</p>
  
  <p>I am currently using Netlify for my frontend hosting and Heroku for my backend hosting.</p>
  
  <p>Could either of these be applying some tags that I can't see/find?</p>
  
  <p>Is my only option to export the project?</p>
