Is it possible to delete drafts?

I think it was possible to delete them before, but now I can’t see how. Can it be done? Some are still there although I’ve submitted them for correction (and the reports are there too, so having just one of each would be great). I thought they would disappear as soon as I sent them. Some are just a few random sentences which I’d like to either delete or copy/paste into other drafts.

Any thoughts?

Drafts can’t be deleted but once you submit them they are no longer drafts. If you still see drafts after submitting them, it is a bug. If you have drafts you want to get rid of, you do end up having to edit and submit them for correction.
