Problem with full bridge rectifier!

hello,Hello, I design below circuit (first figure) for measuring unbalance in three phase system! but there is one problem that I can't understand! when input to bridge (V(N0-V(N)) is like second figure I have the waveformlike third figure in the output of bridge (V(1)-V(2))! It is half wave rather than full wave and also the amplitude is about 10 times to that of input (the probe in figure 3 is 10x) I think the waveform that I see in oscope is wrong. Do anyone know what is wrong!!?!

How are the phase angles defined?

You may need to connect some point in your circuit to ground, the solver seems to need something to hold onto.

If that is a real scope then it will be grounded, you need to use both beams and subtract.
