A few days ago there was a bug with deleting repositories, see this issue for more details: https://bitbucket.org/site/master/issues/17130/removal-of-repositories-goes-wrong.
That problem seems to be fixed but it has caused another issue. The repositories that were "deleted" are now badly corrupted and it is impossible to get rid of them. For example:
- They do appear in the dashboard/repositories overview, but they do not appear in the profile/repositories overview.
- Clicking on the repository results in the 404 page with the message "That link has no power here".
- They do appear in the result of the api request https://api.bitbucket.org/2.0/repositories/$user but they can not be deleted by the api request https://api.bitbucket.org/2.0/repositories/$user/$slug
