[Observium] FortiGate IPsec Tunnels "Missing" From PHP Weathermap

Has anyone else noticed that FortiGate IPsec tunnels are now missing from the PHP Weathermap search box? We've been monitoring a number of tunnels for a while but when I came to update the weather map to keep an eye on some new tunnels, they don't appear in the PHP Weathermap editor, although the tunnels can be found by examining the ports within Observium.

Any suggestions gratefully received.
