IPv6 problem with DHCP

I am running a virtual PFSense to get an IPv6 Prefix delegation from an upstream Fritzbox. I noticed that this only seems to work if I also put the IPv4 connection to the Fritzbox to DHCP. If I try with a static address and DHCPv6 neither the WAN interface nor the downstream interface get IPV6 addresses. Is this normal behavior?

No it isn't. In Dual Stack IPv6 connectivity never may rely on any IPv4 configuration parameter, ever.
Fritzboxes have been acting strange with IPv6 for some time now. There is a quite recent (german) article linking to some issues by heise in c't 10/2016. Your issue isn't in there.
This need to be examined in more detail. Try Wireshark or something and make more sense of the Neighbor Discovery packages (ICMP6).
