Python, Kivy, Ярлыки меняются местами каждый раз, когда я нажимаю «Run», это ошибка?

Вот персонаж

from kivy.uix.image import Image

class Character(Image):  # Character is also Image
    def __init__(self, name, side, **kwargs):
        super(Character, self).__init__(**kwargs)  # because we defined char as an image we need this sentence
        self.name = name
        self.side = side
        self.health = 100
        self.maxHealth = 100
        self.strength = 100
        self.defense = 100
        self.attack_speed = 100
        self.speedBuff = 1
        self.powerBuff = 1
        self.defenseBuff = 1
        self.abilities = {Ability("temp1" , side),Ability("temp2" , side),Ability("temp3" ,side),Ability("temp4",side)}
        self.source = "Pics\chr"+name+side+".png"

В любом случае, это похоже на ошибку, и это действительно расстраивает, потому что это действительно случайно, и оно меняется каждую пару раз, когда я нажимаю кнопку запуска накод, может быть проблема с самим kivy, а не проблема с чем-то еще, и вот изображение того, как это задумано против того, как он иногда появляется
