I still cannot reproduce the issue you describe (a bit confusingly: in rec.games.backgammon you initially wrote "I set one player to Grandmaster checker and cube, etc...", 3-ply then, and the opposite just above). What you could do is to send me a copy of your gnubgautorc file (as it is when you run these tests) and your gnubgrc file if you use one. I could look for difference with mine that may explain the different behaviour. FWIW, when you write (in r.g.b.): "I also just noticed all luck numbers are zeros", that probably means that you don't analyse luck (middle of the first frame in the Settings/Analysis window).
