Setting STOP_MARKET order on Binance

Dear TTA Team,
When I tried to set a new stop loss using the commands provided here:

A new stop loss has been set up successfully on the exchange, but the order type is Stop Limit. Changing to T=STOP_MARKET did not work as intended and the order got executed immediately. Could you help add the option of setting a STOP_MARKET order type as well? Thanks a lot.
