Amortization Chart not showing on submit

The issue is that I’m using oxygen builder for making sites and using the shortcode to display the calculator it works fine and gives me an output as it should, but when I tried the plugin in elementor it had this amortization chart poppup on clicking the calculate button, I want that chart to be visible on the oxygen builder websites too. Any help would be appreciated, cause the output is too plain in oxygen and in elementor it looks eye pleasing.
