[Theme: Customizr] [Plugin: Contextual Related Posts] bug

Hi,
I use the theme Customizr and the plugin Contextual Related Posts.

The related posts aren’t shown correct on my blog, the related posts are shown inside the post article. Here an example: http://blog.bobdapaloma.de/blog/ the post “Videos: Jassim Al Kulaib und Ian Freeman”, there you can see inside the text related posts… and down on the page it isn’t. On all other page it is shown correct.

When I first saw the bug I thought I destroyed it because of trying to much plugins, I am new to wordpress.
So I reinstalled wordpress and the plugin but it wasn’t fixed. I tried also some other related posts plugin, on all the same bug.
I think the theme have some problems with the related posts plugins.
How I can fix it? Or will a update from theme author fixed?

regards
