No FSLTL traffic

Hi,

I have just installed FSTLTL via the FBW installer and upon loading into the sim and starting the injector, no aircraft are being injected. I have all AI traffic off in MSFS settings and so I cannot see any traffic at all. I have checked the log file but no obvious errors and it does actually show what I assume is traffic loading, but the injector doesn't show anything loading. Here is all I'm seeing in the injector:
