Not recognizing Loot-Barrel-1 and Loot-Barrel-2
I am having this issue where Loot_Barrel_1 and Loot_Barrel_2 had the correct loot but not these barrels, Loot-Barrel-1 and Loot-Barrel-2, (hyphen instead of underscore) but adding them manually in the JSON file would help but then revert back on a restart and would be removed from the config, Can someone check this out for us and check why Bradley Crate doesn't register the items from JSON config file ?
I'm having something similar. I'm trying to turn off loot in barrels (event server) and even though I've removed all items, turned the item count to zero and tried to disable as well. about 40% of the barrels won't spawn loot, then there is the 60% that spawns loot and scrap.

I figured it out 
in your betterloot config add these lines, under WatchedPrefabs

"assets/bundled/prefabs/radtown/loot-barrel-1.prefab",
"assets/bundled/prefabs/radtown/loot-barrel-2.prefab",
