This was one I mentioned to Nivex in Discord when he was rewriting the plugin. Now it's been taken over by someone else I just wanted to raise this again in case it's not been addressed.
The config setting...
"Track Explosive Deaths Only": true,
...currently doesn't work. When marked as true, it still logs all explosions, not just when something is destroyed.
It would be great to get this fixed, as it's usually the reason for Discord rate limits when sending the logs to Discord.
