Incorrect maker and taker fees

On TESTNET, when calling /api/v3/account, i got this :

{
“makerCommission”: 0,
“takerCommission”: 0,
“buyerCommission”: 0,
“sellerCommission”: 0,

I was expecting a value of 10 for makerCommission and takerCommission in order to emulate real conditions.

How can i change this ?

commission is 0 in the testnet. I don’t think it’s possible to config from client side.
