Your description of the whole setup is a bit ambiguous, therefore I'm going to assume the capture was made on the switch monitor port. In that case you see the VLAN tagged frames on the ingress port and the non-tagged frames on the egress port of the switch. This is the result of a) the egress port being configured to adding/dropping the VLAN tag, and b) your monitor port is configured to mirror all traffic going in and out of the switch.
