Boss SY-200 Issue

probably more of a Boss question but setting up the new multi-engage-bypass options on an mc8pro and just got an SY-200 is new so threw it into the mix. did the basic setup for a toggle preset for enable/bypass, but encountered something peculiar….

tried a few things, like sending cmd twice but still have to press the switch twice. twice to turn on… twice to bypass. i can’t seem to see anything i’m doing wrong, midi monitor shows expected output. you can literally wait seconds between presses too. other commands working fine eg. preset scrolling, midi exp etc.

have combed thru the SY200 midi setting. any ideas? maybe some weird setting i need to adjust?

dupe sorry; tried forum search beforehand, but eventually found answer via google SY-200 Midi Bypass Issue

weird one, cheers.
