Multilanguage homepage error

Hello,
I have a problem with my multilanguage site.
I am using joomla 3.3.6, Os property 2.7.3 and for template OSPRealty.
I have installed two languages, created 2 menus, made the article associations and cloned the template.
All articles when i click the language icon chage to their association on other language except for the homepage.
When i click it, it gives a 404 error..
Can you please help me?

Also the extra fields when add property dont change to english, although i have translated them all in the tab "translation".

Thank you!
