Have a problem with the Dornier 27

I have just bought the Dornier 27 for FSX. I have a problem with its throttle quadrant. I can't assign any axes to mixture and propeller levers. It wont work. I use FSUIPC for this and select axis assignment and assign my control levers to throttle mixture and prop pitch. Everything seem normal and as expected in FSUIPC and this works fine in other planes. So this is a problem with the Dornier software and not with my controllers. In the Dornier VC I only see the throttle lever move but not mixture and prop pitch. Another odd thing. When placing the mouse cursor over the lever I get tool tip saying throttle but not for mixture and prop.
