You can only delete the content of the post, and change the title.
It seems that right now it will sometimes tell you that the post had an error posting, but that is not true. Then people try to post again because they don't realize that the first one actually worked.
But your original post was 2 days ago, so that's what I did not understand.
I know that my last post content was still showing in the draft after I posted, rather than disappearing like it should have. So did you accidentally hit 'post' again 2 days later?

Yeah I tried to do another post and it was all still there, it wouldn't go away. I hit post thinking it was in "edit" a couple of times, so maybe it would clear, but it didn't... It was treating it like a new post and I didn't want to clear it all to make my new post in case it cleared the original.
Big mess up... But I think I have it figured out now, so I edited the titles to know which ones are duplicates... That should work. Hoping for no more mishaps lol

ah! It is so confusing.
I hope that Steemit can fix these glitches soon.

Definitely!
