A question about Sector Control

Hi there, I have been trying to understand how sector control works and learned so many things so far, yet I have a problem and that is:

Basically, I sync the spawn AI module (that I synced to AI sector tactic and AI options modules) to one of the vehicles I have spawned with editor. The vehicle I spawned goes to the sector with no problem, but when destroyed it is not replaced by a new one. How may I solve this issue?
