Form is not displaying because of an inline style

I have created 2 forms on my site and added them to their respective pages using the shortcode but for some reason one is not displaying, the other one works fine.

Running a plugin/theme conflict test returned the same results so we further investigated it during the chat and found that there seems to be a inline style “display: none” added to it that is causing this.

We added a new rule to the form “display: block !important;” under Appearance > Customize > Additional CSS to force it to be displayed but would like to know why that inline style was added to the form so I don’t need to use custom CSS to make it work.
