Fortilink not working correctly?

[John321]

first time working with FortiSwitches so this is probably an easy fix?

Topology.

FortiGate firewall connected to a FortiSwitch using the fortilink interfaces. Then the first switch connected to another Fortiswitch.

From the FortiGate GUI, I can see the information on switch one, and in 'fortiswitch ports' it shows its connected to switch two by the S/N under the 'native vlan' field. 

But on switch two, I can see the port connecting to switch one is up, but no other information. Also in the 'managed switches' topology view it shows switch two as not connected.
Switch one and two are connected via port22 on both, the switch port config is default and on switch two it created a trunk to switch one, it gets the created vlans from the ForiGate.

Switch two, 
config switch trunk
edit "SwitchOne"
set mode lacp-active
set auto-isl 1
set members "port22"
next

Any help would be apprecicated.
