Мой фрейм Tkinter располагается неправильно

Я пишу интерфейс управления системы "умного дома" собственной разработки на базе Arduino, Python и Tkinter. Код предоставлен ниже. Фрейм container_s1 располагается не так, как нужно (фрейм неверно интерпретирует параметры padx и pady — его верхняя граница находится ниже, чем нужно: очень большой излишний отступ).

Код интерфейса:

    from tkinter import *
    from tkinter.font import *
    from tkinter.messagebox import showinfo, showerror
    from _asQamm.execute import *
    from serial import *
    from pyduino import *
