Inverse Prediction Behavior?

I have a nonlinear fit model based on a Gaussian curve. This means that there should be two X solutions for any Y value when you choose "Custom Inverse Prediction" from the little red triangle. Does anyone know why the program is outputting only the solution from the right hand tail of the curve?

The inverse prediction formula is:
