mod.io not working

Is there a bug in the mod.io editor? People have made mods with it but I can't seem to get mine to make anything but a scout file. I have asked around and still nobody can answer this question. Why does my editor only make a scout file no matter which truck I click in there?

This mod system snowrunner uses is no good. They should have made it like other game (farming simulator is one), where you put a zipped mod into a snowrunner game folder. Simplicity is not one of sabers better aspects.

Where are all the truck files located? Seems I only seen 1 truck file in my game to edit? Why did they hide all the truck files?
