Octaves 5-6 primarily? This isn't uncommon in Yamahas, and 
gray market or not isn't a factor. It's coming from the back 
scale (at least those unisons you knock out playing). Whack 
each unison good and hard once or twice, and re-tune, and the 
problem goes away. Then you just have the usual climate issues 
in churches to deal with.
