Ok, I think I see what your up to. I have seen guys install height speakers where the wall meets the ceiling at the sides of the LP 45° fore and aft of the LP such as the guidelines suggest.
In a 5.1.2 system, the atmos speakers should go just in front of the LP. Like this...
In a x.x.4 the ideal is 45° fore and aft.
In your case, if you can move the jamo’s slightly in front of you, on the side like they are, but maybe as far ahead as your feet would be if you stretched out your legs, would be worth a try. In reality I think this would place them closer to the “Top front” position anyway. Set them as “top front” not front height and see what ya get.
Once you move them, set up the mic and run audyssey bugling through the setup wizard. It should ask about which speakers you have and somewhere along the way, should promt you to select amp assignment for you configuration. There is a manual way to do it. I will look...
