Tp- Link Archer AX3000   

Hello, good morning, I apologize for my English, my native language is Spanish, I come here to expose a problem with my Tp-Link AX3000 Router, I have recently bought it and I realized that the interface when configuring the QoS is different that in my previous router (TL-WR741N I want to add that I feel more comfortable with this interface configuring the bandwidth control than with the new Qos interface of my new router.). I want to limit the bandwidth control and leave some 3 Mgbs clients and I keep the rest of the connection, which is 10 Mgbs, but by setting the maximum egress bandwidth and the max Ingress bandwidth, and I select the clients that I want to have priority, the others continue to receive all the bandwidth as if I had not configured anything. I did the configuration by following these steps https://www.tp-link.com/ve/support/faq/2693/ 

please help me to configure QoS, how am I supposed to set this, to make clients have 3Mgbs and I have priority 10 Mgbs. PS: I have already deselected the priority in the devices that I do not want to have priority and they still consume all the bandwidth
