Multiple IPv6 Prefixes on Client that connected untagged to the bridge

Hey everyone,

I'm having now a weird issue after setting up VLANs on my Hypervisor and pfSense.

Following Network config is currently running:

Code:
auto lo
iface lo inet loopback

auto enp3s0
iface enp3s0 inet manual

iface enp2s0 inet manual

iface enp4s0 inet
        bridge-pvid 100

iface enp5s0 inet manual

iface enp6s0 inet manual

iface enp7s0 inet manual

auto enp4s0
iface enp4s0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 10.0.6.4/21
        bridge-ports enp2s0 enp3s0 enp4s0 enp5s0 enp6s0 enp7s0
        bridge-stp off
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 2-4094

auto vmbr0.5
iface vmbr0.5 inet manual
#TestVLAN

auto vmbr0.120
iface vmbr0.120 inet static
        address 10.10.120.2/23
        gateway 10.10.120.1

auto vmbr0.100
iface vmbr0.100 inet manual

As you can see in my config, enp4s0 native VLAN ID is changed to 100. The reason therefore is, that a client is connected to that.

Now ym Problem is IPv6 for some strange reason. See my pf Sense has the connectio to vmbr0, ID Tag 7 is for my PPPoE Dial in, VLAN ID 100 is my internal net. For every of my VLANs I setup a dynamic IPv6 Prefix. While my Client get the correct IPv4 Address, the Client receive ALL IPv6 adresses from all prefixes.

Now I'm sitting here and asking me, why does the client gets the v6 adresses from a different VLAN?
