Your problem is the capture setup. What I gauge from the capture is that it was taken on the Dell. So how is it supposed to see the unicast response from the SEL451 to the Kalkitech SYNC? When the network switch has already learned the MAC address of it the Kalkitech SYNC the switch port of the Dell won't get that frame, hence you cannot capture it.
So we're left with circumstantial evidence, the repeated ARP Request broadcast by the Kalkitech SYNC. But we don't know if either the SEL451 is not responding or the Kalkitech SYNC is not receiving it. The solution to that is to setup a capture point on the network switch, so you can actually see the ingress/egress traffic on the ports to and from the Kalkitech SYNC and SEL451.
