Signals & Track Automatic Junctions Not Functioning In Editor Play Mode?

So I set up my junctions but when I press play to test a route it shows test junctions in the route window and the automatic routing isn't functioning?

What am I doing wrong?

 

Okay I fixed it by track section tool, I hadn't updated it yet ;u;

 

Hey, I wanted to ask you how did you do that i can't update it.

 

In the tracklaying window make sure you click the signal icon and press fill all.

 

thanks
