Ninja Forms Issue

I have a WordPress website built with the Divi theme at https://www.infocusnet.org/

It has the Ninja Forms plugin in place. Whenever I try to fill out and submit a form at https://www.infocusnet.org/request-proposal/ or https://www.infocusnet.org/contact/ , the form data does not get submitted.

I have already ensured everything is updated. I also cleared the cache. Since one of the plugins in place is WP-Optimize, I turned off HTML and CSS minification in the Divi Theme Options settings.

When viewing the different Ninja Form titles, I was wondering if the coding below ‘Template Function’ is normal:
