Midi recording grand staff not very intelligent

I feel like I’m missing something super basic because while I can get Dorico to record into a grand staff, the results aren’t great. Just for fun, I tried recording the same thing into a file with only a grand staff and the results are much better. I can’t really upload the file due to an NDA but have attaches screenshots. What am I doing wrong or differently to get such different results.

(the better results are from the file with a single grand staff - no other instruments/players)

I realized that posting a project is possible if I cut out most of it. Thanks for the help!

Did you try to extend the caret over both staves?

Yes. It actually makes it so that everything is only in the treble clef,

Probably someone with more hands-on experience on this matter will chime in. I’m not having a midi-keyboard available now to try things
