Extra note added to piece

Steps to reproduce:

1. Hit the record button

2. Play a couple of notes

3. Hit stop

4. Press "Create new piece"

When I listen back to the new piece, whatever the last note is that I press, I hear it twice. It's not in the MIDI file that SeeMusic generates , and there's no visual note for it, but I hear it, and the piano on the screen makes it look like I hit the key twice.

This is on Windows 10, on my Casio CDP-100.
