the ground wasn't on the right place

I moved the ground to every other point in the circuit and keep getting a full wave. I even built a full wave rectifier and it was not converting to DC on the scope. It may be a program glitch. I originally thought it was based on where it was grounded, but even on the full wave rectifier when I moved the ground it showed AC on the scope. Not sure how to report it as a bug...

I m missing a complete question, so i guess its the voltage swing of the second circuit which impresses you? Check the current in both circuits the second one is blocked from current (only a few nA are flowing) the threshold of two diodes is to high for 1V peak, but this little current is what cause the voltage. And the resistor does play no role for nano amps. Only the capacitive part of the diodes do a voltage split 50:50 = 500mV. In circuit one the ratio of current in forward and backward is highly different cuz the diode gets active in forward much more. Hope this helps.

Tidying up Hurz explanation: Diodes conduct at around 600-700mV, you have a voltage drop of≈1.4, which is higher than your 1V source, hence the diodes don't fully conduct, that's why you see the full AC wave
