On the PSR3000 you have to be really careful when using execute and save options. I have never been very comfortable and so I tend to do revoicing on my PC using Michael Bedesem's utility MidiPlayer.

I searched the forum and found a post containing a link although the post is about a different utility PSRUTI which (I think) can do similar things.
