I bought a template, I found the problem, as you said it was a problem on the main template.
Solved by a "div" in the default.php.

Thanks for your attention

Hi, I installed Booking Paid but I have a problem viewing the page "\ components \ com_booking \ views \ subject \ tmpl \ default.php".
In front-end page object is not aligned as in your demo.
Propeties DIV appears under the Info DIV
