Nothing to be sorry about -- you created this topic in the Bugs Forum, which is exactly the right place :-)

I have gotten the error above several times, and I think I've figured it out. The bottom line, for you, is this

If you want to delete a comment you just created, reload the page first.

There is some "state information" that gets saved when you load a page with comments, but which is not updated after you create a new comment yourself. You need to reload/refresh the page (even though you can see your comment :-), then you can delete your comment successfully and move forward.
