Radial turbojets duplicate in the Research center

[hidude398]

When using the stock tech tree, viewing parts available in the "aerodynamics" node of tree reveals that the two radial turbojets seem to duplicate themselves every time the game is run. Upon first launch, all is normal, but each consecutive launch of the game yields a new pair of turbojets sitting next to the original pair in the "Available Parts" window. This issue is only in the research center GUI and appears nowhere else in the game.
