Signals & Track Superelevation Tool Not Selecting Nodes?

Hello,

I'm following along with the editor live stream and the superelevation tool is not selecting the nodes within the track. Is there a part im missing?

This is what im suppose to see:

This is what I have but nothing is working:

 

If you turn up the Node Snap Radius it will be easier to select the nodes. They should turn yellow when you select one.

 

Yep, this was driving me crazy, don't know why it's so low at default..
