I just filed the rail as LDBennett suggested to isolate the switch. It was a little tricky to get at the base of the rail because of the plastic tab. So, I added a tiny piece of electrical tape at the base of the rail. Maybe there's a better way (Dremel tool?) but all I have are mini-files. The triangular ones work well for filing track because they are stiff.
Here are pictures for future reference. Thanks again everyone.
