Problem in Stepper Motor block Parameters with predefined parametrization

I am using the stepper motor block provided in the Simscape toolbox R2020b. I used the predefined parametrization from the provided motors list. The selected motor was Minebea 17PA-KA39B, as seen in the below picture.

From the manufacturer catalog, the motor data are shown in picture 1. The most important are the rated current, 1A, and the holding torque: 610 mN.m. Also, the supply voltage for this motor is 24 V, as seen in picture 2.
The Torque constant is not provided in the motor data, but Matlab provided a value of 606 mN.m/A, as seen in picture 3. It seems this value is calculated as Holding Torque / Rated current = 610 mN.m /1 A, which is about 606 mN.m/A.
I have run a Matlab model with a stepper motor block with Minebea 17PA-KA39B data, and the supply voltage is 24V. The phases currents and Torque are shown in picture 4, and here the differences appear as follows:
1- The Max phase current is 4A, which is 4 times the rated current provided by the manufacturer (1A).
2- The holding torque is 2.424 N.m, which is 4 times the holding torque provided by the manufacturer (606 mN.m).
What is the reason behind these differences?
