IPv6 Prefix Issue

When service was initially setup, I disabled IPv6. Now that I have time to play with it, I enabled it and found what appears to be a routing issue for my delegated prefix.

When I traceroute from a test IPv6 enabled Linode to the external IPv6 address assigned to my router, it works.

When I traceroute to an address within my delegated prefix (listed on the Xfinity modem admin page), packet captures show the traffic does not make it to my router and the last address displayed by traceroute does not match my IPv6 router address, maybe suggesting a routing mismatch?

Any pointers appreciated, thanks
