Impulse or step response of non minimum phase very lightly damped discrete system is different in MATLAB Code and Simulink? One is stable and other is unstable.

Step response of the model G=(-2.6e(-5)*Z^5+0.000126*Z^4-0.0002556*Z^3+0.0002716*Z^2-0.0001503*Z+3.429e(-5))/(Z^6-5.762*Z^5+13.83*Z^4 17.7*Z^3+12.74*Z^2-4.889*Z+0.7814) is very different in simulink and matlab. Even though the poles are just inside the unit circle the system response when using in Simulink transfer function is showing unstable response for unit step.
for matlab code " step(G)" response is
Pole zero are
I have also checked for some other nonminimum phase system with poles very close to unit circle the results are showing unstable response in Simulink and stable in Matlab.
