----------
I do not know whether this is really a bug, but with DS-Lite the IPv4 interface is itself a tunnel over IPv6 and as such an IPv6 tunnel over IPv4 is a tunnel in a tunnel. Also with DS-Lite the IPv4 address is non-global address that may change anytime and connections over IPv4 are handled with CGNAT.

Practical: why not run your IP46 tunnel over the IPv6 interface of DS-Liet ?
