Parentofpeople, it happens sometimes - especially if you have a few versions of CC open at once.
On the desktop version of CC, at the top on the left hand side, there is a list of options; one says “my drafts” - click on it, and you will see all “drafts” that CC auto saved. You can delete them by clicking on the cross that appears if you hover your cursor in the right top corner of each “draft.” That will clear them permanently.
