Display issues Single page with theme Elision and WPBakery Page Builder

We’ve bought the payed version of Our Team for WordPress.
Most things work, but the single page view does not work as expected.
We use the Elision theme. Next to this the WPBakery Page Builder is installed and used. We have a payed erion of both installed.

On the single page view (custom template) the menu is over the content shown. The page is on top.
Also the menu display is wrong, invisible.

All templates for the single post do not work:
Team Member URL Slug does not work as expected. 404 error after renaming.
Popup Card leaves me with a black screen.
and more problems…..

I’ve ‘repeared visual behavior with this:
In the team_members_Template.php:

<style>
    .content {
        margin-top:00px;
    }

.header_bottom {
    background-color: black;
}

And in the style sheet the image for the post is shown 100%. There seems to be an option for this variable in the code, but I can not find this in the settings screens. I changed this in the child theme I made:

.blog_holder article .post_image img {
    position: relative;
    width: 175px;
    display: block;
}

Perhaps i’m missing things. But none of the templates that are provided for a single page view with the payed version work.
Please respond on this …
