ipv4 to ipv6 masq

I currently have ipv6 enabled natively on my wan interface. On one of my internal interfaces does not have ipv6 enabled. On this internal network I can successfully navigate to ipv6 websites such as sixxs.net and testipv6.com. which indicates there is some sort of natting happening. This is unwanted behavior. In checking my masq rules I find that all of them refer only to ipv4 networks. the ipv4 networks masq to -> to uplink interfaces(which includes the v6 address). We use uplink interfaces for a backup wan connection)

I believe this is causing some dns issues as this network is not setup fully for ipv6. We are not prepared to fully enable it now either.

Looking for some advice on this

Here is a snip from the web filter log showing the source and destination ip. Source is IPV4 and destination is IPV6
