I created a sample project with some developers, issues, branches and merge requests. then I presented it and now it's time to delete. but, after deleting from Project's Settings> Advanced > delete project , it is still shown in my project list. though the repository is no longer available , it is possible to import a new repository or files into as well as a "delete project" botton just for me(owner) to delete it. but not works. I closed all issues , merge requests and pipelines in my project, so did members. they closed all issues etc, but still the project/groups appear in first page not only for me, but also for other developers involved. what should I do to remove it from list?
I use self-managed gitlab-ee 14.6.1 omnibus on ubuntu 20.4 and have the owner role on projects and groups.
If you can reproduce it consistently (for any project), that would need to be reported as an issue, similar to 239482 "Admin area project delete doesn't work when project list is filtered".
But I would test it first on a local self-host GitLab 15.0 instance, in case it is already fixed.
If this is only for this one project, it is possible a reference is still not closed, even though you closed MR, issues and pipelines.
That would still be a bug though.
