Title Block Texts – how to change / 3rd text missing?

Hello,

Where are Title Blocks texts stored – e.g. “Join our website free!”.

In price comparison theme setup (v8.9.6) you can change Title Blocks 1 and 2 but 3. text is not editable (see picture) even the element is visible in homepage.

<div class=”media-body”>
<h4 class=”media-heading”> </h4>
<div class=”desc”>
</div>
</div>

I’d also want to understand how the above strings are translated?
