Form cutting off. How do I fix this?

I checked the form https://form.jotform.com/51455945692163 and it displays correctly on both mobile and desktop sites.

Have you embedded the form on a site? If so kindly try embedding using the iframe method.

Could you also provide the link to the site where is it embedded if it is available.
