Help! Anthem STR preamp ARC sounds bad now compared to off


Last time I used ARC, it made an appreciable positive difference.  Smooth, clean, and bass was deep.

I redid it yesterday, using 10 positions, and two subs, and it sounds much better, not louder, better with it off.  ARC is cancelling out all my bass.  It inverted the subs polarity, when i switch it to normal, bass comes back and is powerful.

I wonder if using 10 positions did something strange. 

Note, I also used the phase testing portion of ARC too to ensure speakers and subs are in phase. 

Did I do something wrong? How could it mess up this bad when it seems to have done so good on my first try a few weeks ago?

Anyone wrestled around with best practices here?

Anyone know how to copy settings from Profile 1 to the others?  I can't figure it out and am probably missing something obvious.
Wait what?  It only applies to Profile 1?  Well that changes things.

I actually think 10 locations might have been the problem too.  The first time I ran ARC, I used 5 locations, but never moved the mic from the first position. 
Thanks for the advice.. I might can try again tomorrow.  I can't believe the phasing is only applied to profile 1, that's crazy.
