Problems with search form

Dear Sirs,
We have a problem with auto show room theme.
When we firstly choose a make and a model of a car the site demonstrates only models which are connected with a concrete model.
But, after pushing a button Search and making the same actions on the opened page the site demonstrates the whole list of models

You need to ask the author of the theme however you have no buyer badge on this account and will need to login using the account which purchased the theme before they can help.
