Wrong Laplace result

Hello,

I am using E source to model transfer functions. I am modeling a double pole and an inversed double pole function as seen below

When I plot the responses I get a wrong result, the green curve should have the same corner frequency as the red one, but for some reason it increases. Not just that, the green curve has a lower slope of 20dB / dec when it should have 40 dB / dec like the red one. Why did this happen?

If I model the same transfer functions in Octave I get the correct result shown below

What am I doing wrong?

Regards,

Samo

That looks like bug.

Best regards
