Sitemap problem with wp plugin

I create site using wp + wpl real estate plugin, but I cannot find right sitemap generator that support this plugin.All seo plugins that i try do not add my real estate listings in sitemap, because of that I use https://www.xml-sitemaps.com/ and sitemap is created fine but google wont index my listing to sitemap. Google indexed just 11 pages – main page,categories and about. Web page link : https://www.prestiznekretnine.com.
Please Help.
Thanks
