Loot container chance not working correctly

Good day... I'm not sure if I'm doing something incorrectly, but I have "AirDropChance" & "LootContainerChance" both set to "1" but random booby traps are still popping up on about 1 of ever 3 containers I open.  I've restarted the server and it's still happening.  

How can I make it so that "randomly" depolyed traps are only placed on about 1 out of every 100 Loot containers?

Thanks

Set the chance to 100
I'm confused then.. If I set the chance to 100, wouldn't that make it happen on every container?
