VXLAN RT Problem on Nexus

I have problem in my Eve-NG lab. My Nexus 9000v version 9.2(2) switch gets route from external network, and then adds RT, despite there aren't strings:

 route-target export 65000:10077 route-target both auto evpn 

in VRF address-family ipv4 unicast config. I don't understand why it adds RT. Could you explain me, or show where are my mistake.
