Faceless comment

On one of my melodies, "Umber the unknown" I wrote a comment. When I hit post, a message saying that an error had occurred and to try again later appeared. So, I tried again later. But, the comment I wrote was there, with no user name or account photo. If you click on it all it does is refresh the page. I would just delete it and write it again, but, it doesn't recognize it as mine, so I don't have that option. Is there a way to fix this? Or delete the comment without deleting the melody? If not, it's no biggie I would just like to know. Thank-you for your time!
