OK cool.
Firstly, try hitting the "ratsnet" button - it refreshes all the airwires, and will pick the closest one. If it's not seeing the closer one, check that both traces have the same name. You can do this with the "info" tool, which looks like an eye.
Sometimes though you don't want to route to the nearest location. In this case (and what you can do if it's not picking the right one in general) is start the route, then manual route close to the location where you want to end up. The air wire should snap to the desired location if it is a valid target. If that doesn't happen, again check that the traces have the same name.
