Hello,
As we understand you have problem with your site
essaisitemag.hebergratuit.net/joomla_age...x.php/nos-nouveautes - this is module in menu (and you can not change list). In module there is no option to choose "list" or "default"
On this page you can choose "list" or "default", because in menu you have RealEstateManager Component, not module.

(RealEstateManager :: Settings - House Page Settings - choose House Page Layout or All Houses Layout:
Thanks,
Taras
