Deleted Player still in score

I have a score where I wanted to change a piano to a synthesizer. I added the synthesizer player, copied the music and then deleted the piano player. Unfortunately, the piano part is still in the score and I can’t figure out how to make it go away.
There is no piano on the Players list nor does it appear on the Full Score layout settings. Any Ideas as to how to make it disappear?

Thanks, Bob.

Can you attach the project itself here (you’ll have to zip it up first)? I guess the piano instrument is now being held by another player. Have you tried expanding the player cards for each of the players to see whether the Synthesizer player still has a piano assigned?

Yes, the synthesizer did have the piano still assigned. Once I deleted that, it went away and now all is good.

Many thanks.
