Viewed footsw config doc.
3.5 don't know if same behavior in 3.1
Config'ed footsw1 then tried footsw2, got same behavior.
Prog- to tip, prog+ to ring, tempo to tip+ring.
Tied tip and ring together and with 3A mom switched to sleeve.
Sometimes can set tempo, many times get prog- instead.
To work-around, I'll config with prog- on tip+ring.
Will let you know.
