How to update base fees to 1 in private network?

sumanrajak26

i have updated the config file by putting the below value

COMMANDS=["upgrades?mode=set&upgradetime=1970-01-01T00:00:00Z&basefee=1&basereserve=1"]
By using the command stellar-core --c 'info' it is showing "baseFee" : 1, "baseReserve" : 1,

BUt when i am creating an account, the fees i can check in explorer is still 100 stroops. I dont know what i am doing wrong? is there any way we can change the transaction fees? i have made a private network with 2 nodes.
