If it is hitting weak spots should it be making the sound?

I am trying for the life of me to get this to work correctly... 

 

{
"Automatically gather X Markers": true,
"Automatically gather Ore Weak spots": true,
"BlackList - false, whitelist - true": true,
"BlackList(false)": [],
"Whitelist(true)": [
"chainsaw.entity",
"jackhammer.entity"
],
"ignore blacklist during period": true,
"Give players ability to turn off plugin for themselves": true,
"period start hour": 24,
"period end hour": 24
}

 

I am not hearing the sound you get when using the chainsaw and hitting the weak spot, and im really not sure what im doing wrong. I just want chainsaws to ALWAYS gather the weak spots and not jackhammers, even though i know its set here.  Dev, can you help me out here?

ive got this far... 

 

{
"Automatically gather X Markers": true,
"Automatically gather Ore Weak spots": true,
"BlackList": [],
"Whitelist": [
"chainsaw.entity"
],
"ignore blacklist during period": true,
"Give players ability to turn off plugin for themselves": true,
"period start hour": 0,
"period end hour": 24
}

sounds should work.
