This is a misconfiguration on your end.
Run DHCPv6 client for the ia_pd /48 on top of the PPPoE client interface, from there it will get the /48 from upstream and inject it into the database of the IPv6>Pool.
From there, now, you can just use it directly on each VLAN:
VLAN1- ::1/64
VLAN2- ::1:1/64
Etc
Then configure the IPv6>ND (aka RA) for each VLAN, disable it for "all" (or any interfaces that doesn't need SLAAC).
