That sounds normal to me. Traffic coming in on the native untagged VLAN wouldn't appear on the VLAN interface. I have a similar set up, and I've assigned an unused VLAN as the native VLAN on the trunk, added the VLANs I care about to the allowed VLANs list, and created the appropriate tagged logical networks.

Hope this helps,
