I tried the same the same CC# number and the same ext# as you and I received the same results. I also attempted other CC#s and ext#s and experienced the same. Assigning bypass to Pedal 1 & 2 via an ext# results in the same, so I am guessing that may be a bug. The engineers are monitoring the forums, but I will also let them know about this.
Thank you for your dilligence!
