KIVY TypeError: object.__init__() takes exactly one argument (the instance to initialize)

I have two files: main.py and classbanner.py shown below. I am trying to format a page on my application. But I encounter this error vis-a-vis my classbanner.py code. Can someone help me figure out why do i have this error coming up:

File "C:\Users\JeffO\OneDrive\Desktop\Gym App\main.py", line 162, in MainApp().run()

Your ClassBanner class has properties defined for class_1, class_2, and class_3, but you don't have properties defined for int_class_1, int_class_2, or int_class_3. Just add properties for those and the error should disappear.
