In the section Your work → Projects → Contributed I see a project that I have never contributed in. I have never even cloned or starred the repository. It is not possible to remove the project from the list. I am using gitlab.com in basically default settings. How can I get rid of it?
Did you reply/write/open an issue in that project? If you didn’t do anything in it, then it wouldn’t appear in the list. But as soon as you open an issue, add a comment to an issue, or any other type of activity then it will appear in the list.
