I created my form but the preview looks different

I assume you were referring tot he image on top of your jotform http://www.jotform.us/form/53485982923166

You an reset the form theme first using this default theme reset http://www.jotform.com/theme-store/theme/reset-theme-styles

Then apply your chosen theme again. 

Hope this help. Let us know if this did not work for you.

You may want to just clone also the fixed version I have created here https://form.jotform.com/53486829104966?
