[Solved] Bypass all effects (E) won't unbind.

I've had this issue for a while now where I am strapped into a guitar or bass...(or have to move across the studio to get to a keyboard during the count in) ...I hit the "R" for record ... my finger catches the "E" next door and all effects get bypassed.
The result almost blows my speakers.
Breaks my flow.
Today I thought I'd see if I can move the Binding to an unused key.
It will let me apply the change to this new key.
It won't unbind the "E" key.
 
Without getting into the "Why" of choosing to place those 2 bindings next to each other.... (or why I am not more careful).
Is there some way to unbind the "E" key please?
 
 

Thanks.
