UTM files available but not "painted" on the map

[coregamer700]

I'm trying to import a route into TRS22, but the UTM files won't attach to the ground. I imported both the route folder and the scenery folder, and the UTM tiles already exist as well as the route itself which I can open in Surveyor. However, the route is untextured. I followed normal settings from a tutorial on YouTube and I can't seem to find a fix anywhere, or why this is happening in the first place. Why aren't the UTM files placing themselves?
