Strt problem between GUI and python

Hi all, I used IEEE-39bus model which has 1 GAST2A model.

First, I used GUI to run STRT/RUN. Everything is normal. The message showed below. However, I tried to change this one into python. When I applied STRT API, the results are not the same.

Pls, help me with this case. I really did not know why. The second result is copied from (STRT) .out file when I used python.
