AAA triggering on contact above 2000

[II./JG1_Kadin]

I have been experiencing the following:

On Multiplayer setups, Spawned or activated Antiaircraft artillery remain dormant when a human enemy air contact is approaching at low (<1000) altitude.  It seems that there exists a line of sight on the air target but they just refuse to fire, on most occasions.  I have tried all shorts of AI settings, command priorities and AAA types with mostly a consistent refusal to shoot at INITIAL contact below 1000m.   On the contrary,  once the enemy contact passes 2000m, the AAA start firing as normal at ANY altitude after that.

 

Anyone else notice such behavior?
