Rail track node points missing

When I use the move arrows to adjust roads, I get the blue circles (nodes) to indicate to me where the nodes are so that I can make adjustments. Those nodes used to exist on the rail lines and now they are missing since the Alpha 10 update. In the attached screenshot you should see quite a few nodes for the tracks. You can see the road ones just fine still. The do occasionally show up, feels like at random times.
