Well, to give a little bit of context here,
The same happens to me if I am pressing the momentary switch and I step on a SNAPSHOT button at the same time.
So yes, it *is* a bug.
It is a bit common to lose a bit of balance and accidentaly click a snapshot. In my case, the snapshot I step on when using this momentary switch, is the same that I am currently using and it still locks the state of the momentary switch, forcing me to change snapshot back and forth.
I will upload a video shortly
