Combo box size changes

[hiroshima-shima]

I'm writing Python code using "FreeSimpleGUI 5.2.0.post1" uploaded to the PyPI site.

To create two combo boxes in a window, and dynamically change the contents of the lists in one combo box based on the value selected in the other combo box.When using FreeSimpleGUI, the size of the dynamically changing combo boxes changes to match the total width of the number of characters.This phenomenon didn't happen when using PySimpleGUI.

How can I know to prevent the width of the combo boxes from changing?

I created a sample file and attached it with this mail. Please check it to see what the problem is.

Sincerely yours

main.py
