Different angle of approach in same flight

[combatace]

I've seen this since I'm using FC1 and it is still there in FC2. Me and my wingman both have a different angle of approach for the run way. I don't understand this, even though I select A/P for landing than why does this happen?

 

I have attached some pics to support my point. One can see the difference in the angle of LERX in both the planes.
