A real shot in the dark here:  The SP-H9 has a toe switch, as I understand it (never used it).  Is it possible that internal switch on the Mission is ‘stealing’ the right footswitch from your Ampero?

I would try this:  TS cable out from the Mission expression pedal.  Or better yet, unplugged from the H90 completely.  Try to calibrate the Ampero dual switch on its own, using a TRS cable.

Then unplug the Ampero, use the same TRS cable to the Mission, and calibrate the SP-H9 by itself.  First as an expression pedal, then re-calibrate it as an Aux Switch, while pressing down on the toe switch.
