Can you please help, While this does compile without errors below, its not charging players 1000 for removal, it says Free

"generator.small": {
"Remove Allowed": true,
"Display Name": "Test Generator",
"Price": {
"generator.small": {
"amount": 1000,
"skinId": -1
}
},
"Refund": {
"electric.generator.small": {
"amount": 1,
"skinId": -1
}
}
},

I thought it might be because of the entity name, but its not the case.
