Stuck importing repository from GitHub

I imported a repository from GitHub, which went well and took less than a minute.

However I forgot some uncommitted work. So I deleted the Bitbucket repository, did my commit and did a fresh import. This time around the importer got stuck, the progress bar shows around 80% and the console underneath is empty.

After being stuck here for more than half an hour I navigate away. If I return to the repository it shows the bar progressing again, but eventually gets stuck in the same way. I tried making a second repository with a new name which also got stuck in the same way.

I rebooted my machine. Both repositories are still stuck. So I did a third repository which worked perfectly and just as fast as the first time. The console also showed the importing process.

I now have a working repository "JustInTime 3" and two repositories stuck in import which I cannot delete because settings are not available before importing is done "JustInTime" and "JustInTime 2". Are there any way to delete the two repositories which are stuck? Will they eventually timeout?
