I cannot get the sostenuto and soft pedal to work on yamaha p125. the right sustain pedal works. anyone else seen this problem?

I just set up my p515 and I am having the exact issue you’re having. The rightmost pedal does sustain but the other two pedals seem to have no effect. Have you found a solution?

Yamaha P125 is what I use. It integrates perfectly. Check the Amazon site for the pedal unit and add your piano to find a perfect match. Mine works seamlessly with this pedal unit.
