I'm having a problem keeping a default setting on footpedal #2.

I have pedal #1 set to sustain and stays set to sustain which is what I want.

Pedal #2 is not working the same way.
I go into functions to set the pedal at 'fill', and it works as 'fill' until I change from the current registration or song, to a different reg/song.

How can I prevent pedal #2 from changing whenever I change registration, song, etc?

It automatically sets itself to 'volume'.
