Military bases do not attack

Hi, 

I have build a base near the entrance point in my sector, I am at war, however the station doesn't attack the enemies even when they are stationary inside their bubble.

Had enemy fleets stationed next to the station (touching it), still they didn't got attacked. Other fleets just pass through the bubble, no damage either. (see the fleet is inside the bubble).
