PMDG 747-800X Cockpit problem

[Xizzle 0]

Hey guys, my name is Charlie
I just recently bought the pmdg 747X and im new to this plane. Ive been messing around with it and working it out and i have come across a problem that i cant work out  
When I am told to raise my altitude and press (f10) to go to 2d cockpit and adjust the knobs for alt set, I can only tune them down and not up, this is the same as my heading knob and speed set knob. Can anyone tell me about this problem?

SORRY I MEANT 747-400x

I have the same problem. This happens with all the knobs that can be adjusted. They only move to the left. Have looked at a lot of forums and can not find anything that could be causing this.

if anyone could help that would be awesome.
