Footswitch pedal issue

Hi,
I have just bought a Yamaha FC5 footswicth and I am trying to understanding how to use it for recording some sequences with synth patches. However it does not work at all…

Furthermore, I am also noticing that the organelle does not work very well when I input this pedal, say the control knowb freezes and no patches can be selected anymore.

What I should do? Is this a specific conflict of this pedal? if so, are there any other footswich pedals that works properly?

Thanks,
