Why I see other unicast from a switched port?

I use the span on Cat5500 to troubleshoot a problem, after I looking into the trace, I see some unicast from the switched port.

Shouldn't I only see the unistcast in/out from the device on that port and broadcast or multicast? Why I seeing some other unicast from that port?
