Are you sure the Vol and Wah FX blocks Position parameter is properly assigned to the EXP1 and EXP2 pedal controllers? That’s the default but if those controller assignments have been changed it explains your symptoms.

I recently updated to firmware 2.50. I'm not sure if it is connected but I have exactly the same issue - the expression pedal toe will select between Exp1 & 2 but it does not alter the volume or wah effect anymore.

I've checked the assignment of Volume to Exp2 but it makes no difference.

 

It is just outside the two year warranty that the shop gave me and it is the second unit I've had in just over two years! (The first unit failed in a different way though.)
