what you have done is that is not the right way i.e. to use the text editor / css hacks.
i am really concerned with the Elementor style option, you can see that red color selected in elementor style tab is not applied to the text. because that is not changeable globally when you have to change the color scheme overall.
so please try fixing and letting us know thru the elementor way so that the proper and profound use of elementor widgets should be solved and applied.
Well please use the heading elementor widget there instead of text editor , if you use text editor the editor styling takes over , as you can see its not working even on the elementor edit page.this is not a theme issue you can further contact elementor support on this.
