Autoconcede msdeley

[matter]

how can i change the Ms delay on autoconcede in DefaultBot.json? because every time i change

"AutoConcedeMinDelayMs": 15000,
"AutoConcedeMaxDelayMs": 30000,
to
"AutoConcedeMinDelayMs": 3000,
"AutoConcedeMaxDelayMs": 10000,

the value auto changes back to default, why?
