Track Markers Not Working Right

When trying to add siding, platform. and destanation markers they don't work correctly. With the siding marker I don't get a middle "pole" along with the two end ones. I can't extend it. When extended, it snaps back to the center. With the platform, I can't extend it in either direction. The destanation marker can't even be placed. I tried saving and giving it another try without luck and exiting the sim and reloading the route doesn't fix things either. I've never had this happen in 13 years of using TSC/Railworks. Thoughts?
