HOME Mode: In polar, angle did not change between RAD <-> Degree

[akmarul]

Hello all,
In HOME mode, and say I have 5 stack of polar numbers; 5 angle 45 degree. if I try to change the angle from degree to radian, through the upper right screen, PRIME never change the angle of all the polars numbers on all 5 stacks automatically to radian. Is this normal/bug? Usually what I did, I hit APP button and then hit HOME button, to get all the angle change to radian (or vice versa). Thanks. I am using G2 and have the latest FW.
