We are 525 sorry about that, fuzzy memory, what was I thinking.  Just as Richard posted earlier can't see the switches with the slide in.  The difference in your slide configuration and ours, the upper slide locks were not extended.  Have you tried to retract the slide locks only and stop the slide sequencing before the slide moves.  That would set your HWH logic board up in a similar condition as ours at that time.
