AAA destruction without point credits

[machtu]

I have noticed lately that when I attack enemy aaa batteries at airfields with icons, when I return to base and land there is only a partial or no credit for number of batteries that were destroyed.  Last one  was where I destroyed 5 batteries but credited for only one.

 

Is there a reason for that?

 

Thanks for your attention.  Thanks for all  your efforts, a great server.
