Unwanted cross-staff kneed beams for piano with centered \dynamics

[Sam Bivens]

Hi all,

In the attached MWE, I want to remove the kneed beam. The problem seems 
to be the centered dynamics, but I'd rather not remove that.

Is there a solution to remove this kneed beam, or an alternative to the 
centered dynamics that wouldn't create the problem in the first place?

Thanks!

Sam
