I have default group assigned to "Permission:": "autopurge.7d". 
I have admins group assigned to "Permission": "autopurge.nopurge".

Admins keep getting purged after 7d, and is not honoring the Lifetime: "none" setting which i have set for the admin group..

{
"Purge Settings": [
{
"Permission": "",
"Lifetime": "7d"
},
{
"Permission": "autopurge.7d",
"Lifetime": "7d"
},
{
"Permission": "autopurge.14d",
"Lifetime": "14d"
},
{
"Permission": "autopurge.nopurge",
"Lifetime": "none"
}
],
"Purge Timer Frequency": 3600.0,
"Purge On Startup": false,
"Entities Per Step": 512,
"Purge Building Blocks": true,
"Purge Deployables": true,
"Purge Sleepers": true,
"Use Logs": true
}

Maybe I need to unassign the "Permission": "autopurge.7d" from the default group ?  Will the plugin then honor my "Permission": "autopurge.nopurge"? and the default users will be automatically handled by the first empty permission ?
