N1 transient arc and autotrim

Good evening again,
sorry for posting so much the last days, the more I get involves in your fabulous piece of programming, the more questions arise...
#1 (only cosmetic) the transient blue arc on N1 instrument should be (if I recall correctly and I stand to be corrected) between N1 actual and thrust lever position dot, now it is between idle and N1 actual
#2 more important to me
I´m using your Project Airbus Plane and in the AP/FBW module PA320 is highlighted. When airplane is level in flight an I command 20 degrees bank, it should maintain altitude but instead it goes into a slight continuous descend.
Am I doing something wrong the flight model ?
Once again, thank you for your fast replies and patience,
Toulouse
