Iperf flow is not assigned to queue

I'm new to ryu rest QoS. I'm trying to create QoS queue and divide bandwith link to two iperf flows.
First flow max-rate is 300Kbps.
Second flow min-rate is 700Kbps.
Link bandwith is 1Mbps.
Problem is both flow are using circa half link=500Kbs.

Here is link to Ryu Rest QoS tutorial
