Hi Shane,
I have add on our serveur a zip archive of template Kalium
/www/xdev
themeforest-10860525-kalium-creative-theme-for-professionals.zip
You have ftp access.
So the issue is that when a theme does not use the_content() to render Post Body Content, usually Content Templates, Template Layouts and Content Layouts will not be applied to the Posts even if assigned.
What you will need to create a Child Theme and add at least a single.php Template to it, where you will call the_content() or the_ddlayout() along with the other (default parent theme) stuff.
What I recommend that you do is to contact your theme author and allow them to assist you with the child theme creation or you can continue with just using our views plugin to do your custom templates.
