This thread is resolved. Here is a description of the problem and solution.
Problem: Everytime I update banner text, it converts to German text.
Solution: It looks like you are using Revolution Slider to display the homepage banners. I see that you do not have the homepage slider set to Multilingual. Please follow the documentation here to translate the slider content: https://wpml.org/documentation/plugins-compatibility/creating-multilingual-sliders-with-revolution-slider-and-wpml/
