Event list-page, everything is "float:left" – why?

Hello,

i just finished editing my wp-theme when i discovered everything in my events list-page is floating left.

Ive uploaded a screenshot for you:

Also the event_form-page is floating left completely.

I already checked all the templates i could imagine which are able to cause this. F. e. header.php, single.php, page.php, index.php, and so on. I wasnt able to find something like “float:left” for any css-class which is provided for Events Manager in style.css or in templates.

Thanks for your help.
