If Entering A Transfer Function Via "roots' Instead of As Polynomials, The Step Response Is A Bit Degrated #1246

Hello community,

I am simulating the response of a buck converter along with a Type III compensator. As I am developing two Type III compensator functions, for flexibility in how I might enter the compensator values, either as roots or as polynomials, I noticed that if I enter the compensator values in polynomial format, the response is ideal. However, if I enter the values as roots, the step response is less than ideal. The following screenshot is the step response using the same Type III compensator transfer function but entering the values both as 'roots' vs. polynomial format.

Has anyone had similar experiences? If so, is there a workaround?
