I found out already. It is because I make a table inside table in contact form 7 code.. It was ok with my previous themes. But I’ll find another solution for this.
If you wondering what is my contact for structure, the sample of my contact form could be found in http://www.villabugis.com/villa-alore in the booking tab (or other villa post) Now I have to take out the YM and skype link inside contact form
