IPv6 not working on boot, but after editing WAN interface

The system is on the latest version

I have a static /128 framed address for WAN and /56 delegation from my ISP.
"Your IPv6 access device/router should assign /64 subnets to its interfaces after it obtains a DHCPv6 PD lease. It should then offer the prefix to your hosts via IPv6 Stateless Address Autoconfiguration."

I have configured WAN interface for DHCP6 with no extra settings in DHCP6 Client Configuration, expect the prefix. LAN set as static to a /64 subnet. It seems to work fine everything reports up, however if I reboot pfsense the WAN interface will not get IPv6 address, LAN is fine as it is static, (not routing out though). I have SLAAC set to "Assisted" and DHCPv6 server running for a range in the LAN /64 subnet. I'm running pfsense on a single port device with vLANs for LAN and WAN, re0.10 (WAN) and re.0.1 (LAN).

If I then edit the WAN interface but not change anything after applying IPv6 is back up? ifconfig <dev> down / up doesn't force it to work though

I had previous used these settings but they had a worse issue where they wouldn't get any ipv6 or ipv4 addresses,
Under Advanced DHCP6 Client Configuration

Send options: ia-na 0, ia-pd 0
Request options: domain-name-servers, domain-name
Scripts: /var/etc/dhcp6c_wan_dhcp6withoutra_script.sh
Identity Association Statement:
Non-Temporary Address Allocation: checked
id-assoc na ID: 0
Prefix Delegation: checked
id-assoc pd ID: 0
IPv6 prefix: ::/56
pltime: infinity
Prefix interface statement:
Prefix Interface sla-id: 0
sla-len: 8
Prefix Interface: LAN

Is there something simple I am missing?

maybe "Get IPv6 through IPv4"
