Xara Designer Pro: My submit button does not appear

I have used the basic contact form template, and having customised it, when I embed into Xara Designer Pro, the submit button does not appear. I have tried to stretch the size of the widget vertically, but it still does not appear.

I am at a loss as to understand why?

I have not yet published the page onto web.

I don't know why or what to try....

Since your form submit button and other fields are being properly displayed on the online form, the issue is most likely related to the form placeholder element size on your web page. Please try increasing the size of the form placeholder element in your web design software.
