The forms I am creating are not previewing or publishing in full. How can I fix that?

I have checked the last form you have edited and found it loads properly: 

Which embed method are you using? 

May we get the webpage where the form is embedded on? 

This will help us to see how the form embeds, you may also provide us a screenshot about how the form loads on your end when previewing it or when loading the direct link. 

This guide will help to upload the screenshot with your next reply: How-to-add-screenshots-images-to-questions-in-support-forum

I have also cleared your forms cache so they load now with the latest version.
