Unable to import project from github

We are in middle of migration of our projects from github+travis to gitlab.com.

We’ve a private project on github and few days back I had migrated this project from github to gitlab using github import feature on gitlab.

Today I went ahead and deleted this project from gitlab and tried to re-import the project again into gitlab, however now I am unable to see this project anymore.

Also I am unable to lots of other project inside of my organization on github which I’ve not imported to gitlab yet.

Any ideas what can be done to fix this issue.
