Okay so I figured out the issue, I'm guessing this was caused by an update on ED's part.
Basically on the Shahed136_LM file I had to change "Reflection = 0.1" to "Reflection = 0.15"
I'm not sure if this is the radar cross section or not, but I had the drones fly within 100ft of the ai aircraft with the value at 0.1 and then at 0.15 the ai will engage the drones.
