Hi there,
The title overlaying the image is intentional – this theme is designed to use featured images as large, full-width headers on the single-posts and pages, with the post title layered on top. You can see this in action on the demo page, here:

It’s possible to move it using CSS, but the code is a bit complex as a lot of stuff needs to move, and you need separate CSS for different screen sizes so it looks good on mobile and computer screens.
This is the closest I’m able to get it:
@media only screen and (max-width: 640px) {
.libretto-has-header-image .title-block {
position: static;
background: #faf9f5;
margin-top: 280px;
width: 100%;
}
header#masthead.site-header {
margin-bottom: 0;
}
}
@media only screen and (min-width: 641px) {
.libretto-has-header-image .title-block {
position: static;
background: #faf9f5;
padding-top: 20px;
margin-top: 380px;
width: 680px;
box-shadow: 2px 2px 6px rgba(0, 0, 0, 0.05);
}
header#masthead.site-header {
margin-bottom: 150px;
}
}
@media only screen and (min-width: 860px) {
.libretto-has-header-image .title-block {
position: static;
background: #faf9f5;
padding-top: 20px;
margin-top: 380px;
width: 782px;
}
header#masthead.site-header {
margin-bottom: 120px;
}
}
.libretto-has-header-image .title-block div.entry-meta, .libretto-has-header-image .title-block div.entry-meta span a, .libretto-has-header-image .title-block div.entry-meta:before, .libretto-has-header-image .title-block div.entry-meta:after, .libretto-has-header-image .title-block h1 {
color: #787065;
}
For any further customization in this regard I’d recommend you look into getting help from a professional developer instead.
