Thank you for contacting us Sam and I am sorry to hear about the problems removing that widget on your home page.
The Wedge theme used on your website is one of our classic WordPress themes, and the Call to Action widget area is tied directly to the Home page template in that theme. It looks like you might have switched your Home page to use the default template, instead of the Home one, which does not display the Call to Action widget.
If you are looking for a theme with even more customization options then you might want to try out Crio, our newest WordPress theme, which has a more powerful version of our theme framework than the one used in Wedge.
Please let us know if there is anything else that we can help with!
