British Airways or American Airlines Messed Up Avios

I'm not sure who's fault this is, but something is broken.  American Airlines is listing first class on a CRJ-700, a two cabin airplane, as first.  British Airways' Avios is charging it as first class on a three cabin airplane.  This award should be priced at the business class rate and be 1/3 cheaper (18,000 miles rather than 27,000).  One or the other is messing up and destroying the value of the Avios program.  Since I need to blame someone for my unnecessary frustration, I'll say it is BA's fault for not pricing awards correctly.
