I am having major issues trying to implement the multi-step form on my client's site. I hit save continually and will see the changes in the frontend, and then the changes will suddenly revert back and I will lose hours of work. My updates are nowhere to be found. Also, CSS styling that I make/see in the backend isn't appearing on the frontend. I had to add CSS styling manually in the Customizer.

Any help you can provide would be greatly appreciated.
