v1.1 M18A1 doesn't blow up cache

The M18A1 Claymore doesn't blow up weapon caches. I tried using 6 charges and it didn't blow it up.

Also, I tried blowing up the yellow one when running (not sprinting) and the charge didn't went off.

Is there a way to know if the cache is taking damage? I tested with the stinger, it made a cache impact noise, and I tested the MBT Law and I'm not sure.
