Point 2 looks like as if point 1 would be mirror to the middle point. It is curious. With a parallel cap you never go from 1 to 2. The bigger the cap the mpre looks your circuit like a short and the closer you are to point (-1:0).
Point 3 and 1 isn't on a constant reactance curve.
So yes, something is strange in your results.
