DHCP relay on Guest wifi gets wrong ipaddress

unknown

I have 2 scopes set in DHCP one for school network on 10.64.x.x and then one for 192.168.x.x, (Guest_wifi_Vlan  ssid) i have set up dhcp relay in the ZD for this ssid, ive clicked tunnel wlan traffic to ZD option and ive ticked the enable dhcp relay agent with the server details. But for some reason i keep getting allocated an ip address in the 10.64.x.x range, what am i doing wrong or missing at present no vlans setup (apart from default vlan 1) also i have a normal guest wifi whihc gets its detaisl from the 10.64.x.x and present a wifi logon box fine.
