Key command confusion

I set up a key command to bypass all inserts on selected tracks in the mixer (I =Toggle Inserts Bypass Of Selected Tracks) under the Key Commands under Process Project Logical Editor.
When I hit the assigned key the inserts go on and off in a cycle from some tracks to other tracks. I presume I’ve made a mistake here but what? I did exactly the same procedure for a bypass eq on selected tracks with a key command and it works as expected.
Any help gratefully received.

Hard to say. Would you mind snapping a screenshot of your PLE preset?

Hi mlib,
On my other pc with Cubase installed the key command works perfectly and as far as I can see the settings in LE are the same on both machines. Would trashing my preferences be a way to go? Thanks.
