Does your router send RAs for both subnets on the guest wlan? Run radvdump on the client to check this. Probably another device sends RAs for thw wrong subnet? Check /etc/radvd.conf on the router to ensure both wlan interfaces are configured properly. Does the router use the correct nestmasks for both subnets?
I left Wireshark running on that interface for several hours, capturing only ICMP6. With no devices connected, all it had were the router advertisements. Every one of those RAs showed the correct info. Radvd.conf has the correct info and the subnet mask on both subnets is /64.
Wireshark on the client computer i guess. Running radvdump is probably easier. You should also grep for the ipv6 address in /var/log/messages to see how the address is set. Look at /etc/sysconfig/network if you have a fixed IPv6 configured there. Then - if you use network manager look there. You can run nm-connection-editor from the command line.
