Ion fader wing bump problem

Since updating to 2.33 the first time any bump button is used after the Ion boots causes all subs to full on state.  After resetting the subs to zero subsequent use of the bump buttons is as expected.  Since we have the house lights on a sub, this is a big problem as they come on with that first use of a bump button.  Any ideas as to what is going on?

Thanks, Ken
