Corrupted repositiories due to failed imports

I migrated all repositories from our self-hosted gitlab to bitbucket, and everything went smoothly except 2 of our repos where the import process hanged.
Now I have 2 repositories (psycholate/carpe and psycholate/graduace-old) which are corrupt and totally inaccessible.
I'd like to delete them in order to re-create them and do the import again (I will do remote add and push from y local copy this time instead of using the bitbucket import tool), but I can't get to their settings page in order to delete them.
Can you help?
