Chainsaw (and krieg chainsword) not working but jackhammer is.Bug

hi, thanks for making this plugin!

it seems that the plugin is working fine for the jackhammer but for the chainsaw and krieg chainsword it isnt working. i added the config here: 
{
"Automatically gather X Markers": true,
"Automatically gather Ore Weak spots": true,
"BlackList - false, whitelist - true": true,
"BlackList(false)": [],
"Whitelist(true)": [
"chainsaw.entity",
"jackhammer.entity",
"krieg_chainsword.entity"
],
"ignore blacklist during period": true,
"Give players ability to turn off plugin for themselves": false,
"period start hour": 0,
"period end hour": 24
}

Hi! thank you for letting me know, I will take a deeper look into this issue
