Kea DHCPv6 Issue on HP Aruba 5412R Zl2

We've been trying to do some testing with dual stacking but have come across some weird behavior. When we run our Kea DHCP servers, DHPv4 is able to give out IP addresses but DHCPv6 does not. Machines are receiving IPv6 addresses, but the Kea server isn't the one giving them out (We turned off Kea DHCPv6 and machine were still able to get IPv6 addresses).
