Is it possible to delete a backup using the control panel?

I created a droplet, with backups enabled, then, a few minutes later deleted it. This triggered the making of a backup before the droplet was deleted. Now I have a backup, with no corresponding droplet. The only option for managing the backup appears to be an option to convert it to a snapshot. I did that, and the backup disappeared. But it reappeared soon after I deleted the snapshot.

Thank you.
