I think you misunderstood me - I'll clarify again.
Zen give you two prefixes - a /64 and a /48. The /64 is for the WAN side, and used purely for the purpose of allowing your router to auto-configure a random IPv6 address under this /64 assignment, on its WAN interface. Looking at your screen shots, it has already done this successfully.
Now the next part.
The /48 they give you is for use on the LAN side. It is routed via the /64 IP address that the router auto-configures itself with on its WAN interface. But, you need to tell your router what /64 prefix (and there are 2^(64-48) = 2^16 = 65536 different /64 prefixes to choose from) it should use for the LAN interface. So, set the "Static LAN IPv6 Address Configuration - Interface Address / Prefix Length" to be:
(which is the same as 2a02:8010:8001:0
::/64) - the 0
is the very first /64 prefix you can use from 2a02:8010:8001::/48, which they've delegated to you.
You've currently set the "Interface Address / Prefix Length" field to the /64 ND (Neighbour Discovery) prefix Zen gave you (2a02:8011:d008:1::/64) which is incorrect. This may still work, but it is not the way Zen intended this /64 to be used, in a routed setup.
