Hi Uncle Dave,
I normally just play in arranger mode,
the settings you're using to play bass l/h , melody r/h

are you using the "manual bass" to acheive this ? with Memory & Bass Inversion buttons set to OFF.

I've tried a couple of dozen styles, and I can play bass thru ending 1 using the above setting.

What I did notice though, I accidently turned on the "lower" Chord Scan button, which automatically turned off "Manual Bass" hence I lost bass, is it possible that this may be happening to you.

Just name a couple of styles that aren't working for you & I can check mine.

Now, on to my small speed bump with style play - I notice that only a few patterns shut the LH sound off during the "ending", and it seems like it's specific to the 1st ending. I'll have to do some digging to see what parameters might be available to disable this annoying feature, and I sure hope I find one - the drums are SO good in this piece, and it'd be a shame if I just lost the ability to trigger a LH sound during an ending ... with or without an arranger playing.
