Tunnel interface doesn't show up in routing table (Fortiwifi 90D v5.4.4)

Hello,

I tested in LAB a fortiwifi90D with IPSec tunnel hub and spoke. At that moment I had a WAN link connected to my fortigate, now I disconnected the Fortiwifi from the WAN in order to  change the test IP used in the LAB for the real ones (so tunnel is down). After that, I realized that I haven't a route for the remote address, but when I tried to configure the route for the subnet in the other side of the tunnel I don see in the route table/new static route / device the tunnel interface option. Is it a normal behavior? because in others Fortigate, even when the interface tunnel is down, it shows up in the route table as an option... Thanks in advance
