Guess, you have configured VSPAN to monitor the traffic on particular vlans. I suspect the problem here is with the ports on the administrative VLANS. Check this extract from the following document :
VLAN-based SPAN (VSPAN) is analysis of the network traffic in one or more VLANs. You can configure VSPAN as ingress SPAN, egress SPAN, or both.

The destination port, if it belongs to any of the administrative source VLANs, is excluded from the operational source. If you add or remove ports from the administrative source VLANs, the operational sources are modified accordingly.
