Cannot add or delete songs

I just uploaded the Pro version and here’s what happens:
– I created a playlist and added an audio track.
— I filled out the song information and clicked “Add Song”. I got the message “New Song Added” was added.
— However there doesn’t appear to be a way to add a new track after you’ve entered one already. When I clicked “Add Song” again, it created a duplicate entry in the play list
– I attempted to delete the duplicate entry (hovered the mouse over the play list name; clicked “delete”) but it would not delete the track.

Thank you….
