Betaflight receiver preview

Hi I have a problem with pitch in the receiver tab I am running CC3D, SBUS.

When in the receiver tab the model image in preview changes direction for aileron and rudder but the pitch doesn’t move, ie I see the stick slider moves left and right as per all the other controls but this doesnt change the direction in preview, any ideas would be greatly appreciated. just to see if I could narrow it down, I connected to cleanflight it seems to work as expected in that app and have tried windows and mac and get the same result across both platforms. thanks
