Which of the forms on your account is embedded on your website? I would like to apologize, but the screenshot you have posted came out blank. Can you provide us the form and the link to your website your form is embedded so we may look into it? Although, I'm not particularly sure if the issue to why your form is cut off is caused by conflicts between your form scripts and the scripts on your website, I would still recommend you to try embedding your form using the iFrame code.
