Hotel Rooms Display Page Broken

Hi!
Just purchased my Booking Plugin that looked like just what I need but when I set my Rooms Display page, that page shows broken, I mean the content is there but my theme header and footer is gone, there’s a sidebar I’ve never seen there before and some weird footer, just bad looking, I don’t want to change my theme just for this plugin, please help on at least putting the plugin content inside of a page where my basic theme design is (header and footer).

Thanks.
