COIN-M Futures Transaction Fees

Hello,

Recently I got my hands dirty algotrading some BTCUSD_PERP on COIN-M Futures on Binance because of the really low transaction fees for market makers (0.01%). I don't know what I'm doing wrong, but no matter the order type (LIMIT or MARKET) I get taxed a 0.05% fee (the fee for market takers).

Seeing this, I've created some manual LIMIT orders and strangely I still get taxed the 0.05% although I am not buying at market price. Do you know what may cause this?

Thanks.
