How to show testimonials page title on front page?

You can accomplish this with some custom CSS:

.front-testimonials::before {
  content: "My Testimonials Heading";
  text-align: center;
  width: 100%;
  font-weight: bold;
}

You can tweak it further as you like to adjust the size, colour, etc.

Don’t edit the theme files directly, otherwise your changes will be overwritten every time the theme is updated to the latest version.

An easy way to add custom CSS is to install the Jetpack plugin and activate the Custom CSS module. You’ll then add your custom CSS in the new stylesheet editor that’ll appear in your dashboard, under Appearance > Edit CSS.

As alternatives, you could either install a standalone custom CSS plugin, or create a child theme.

Okay, that code fix the problem, but I guess that developer should fix that issue on theme.

Glad that did the trick.

The testimonial title is intended to be displayed only at the top of Sela’s automatically generated testimonial page – not on the front page – so it won’t be changed in the theme.

You can get to your dedicated testimonial page by adding /testimonial after your URL. You can see it in action on the Sela demo site here:
