Problem with QoS N3K & N9K

I have configured QoS in two SWs, Nexus 3232 and Nexus 9336, the input policy is working ok, traffic is match wiht it, I can see packets inside it, but output policy isn't working, I can't see any packet that match in it, it is empty.

This is the configuration I have use.

Today I did a capture of service policy output


SWSCP-CPD-ACC-2#
SWSCP-CPD-ACC-2# sh policy-map interface port-channel 100 output type queuing detail


Global statistics status : enabled

I can see the q3 has packets droops. Is that normal or must another queue has packets?
