Raids being counted in excess

I have an armored door. 
I place one timed explosive.  My raid count goes down to 2/3 remaining (expected).
I place another timed explosive.  My raid count goes down to 1/3 remaining - on the same door...same base....same owner.
I place another timed explosive.  My raid count goes down to 0/3 remaining- on the same door...same base....same owner.

Shouldn't that not be the case?

You're correct that should not be the case

why do you think this is happening?

I'm not sure at this moment, do you have any other details, does this happen all the time? Or just sometimes?

This happens every time.

Just now, Rust Admin said:

Here is my config:
