Custom content

I have set up everything using Customs Content and HTML code. Everything is working, I have also made two templates - one for wide screen with 3 testimonials and one for mobile with 1 testimonial with slider. super. But The Custom Content has to have Title - its called Heading. I have used "Testimonials", but now when I have 2 of them, its showing two times Testimonials on the page, one is empty (due to custom CSS) and one is normal. This Heading cannot be empty. How to solve this?
