DHCPv6 issuing IPs from VLAN30 to LAN Untagged, Why?

[davidg1982]

I have a relatively simple network setup, but I am having an issue where my VLAN30 DHCPv6 is issuing IPv6 prefix 3 IPs to my LAN untagged network, and I have no idea why. Each of the interfaces IPv6 is tracking the WAN. Router Advertisement is Managed. The Prefix Delegation for each of the DHCPv6 VLANs is /64. I have nothing in the Prefix Delegation Range for each of the DHCPv6 fields.
Not sure what else to add. I really appreciate any help you can provide.
Running 2.7.2-Release, which is the current version.
