Positive cabin vertical speed in cruise

[Rezab]

Hi

just wanted to know if these are known bugs or just something I am experiencing, or something I am doing wrong:

 

-In cruise, my cabin vertical speed remains at positive 50fpm the entire cruise. Is this normal or should it be zero? I have seen many Inibuilds YouTube videos where it is zero for other Youtubers.

 

-During climb, at higher altitudes, the aircraft pitch/nose keeps fluctuating. Thrust pushes speed high, nose pitches up to a higher vertical speed, then speed drops and the aircraft pitched down to lower V/S. This continues until CRZ alt is reached. This is in managed mode.

 

Appreciate any input/feedback.
