It happens all the time, but I don't think there's anything you can do about it. One of the remaining shoot will take over as leader and grow more vertically. When I have that red or white pines with that problem, I just keep an eye on it so two leaders don't form, which would create a fork in the tree. If you have two branches that look like they will be dual-leaders, just cut one off so there's only one leader. The tree will have a little crook in them to begin with, but as the tree grows in diameter it will be less noticeable.
You seem to be getting good annual growth on your red pines, where are they planted and what kind of soil do you have there?
