Multisite Domain Mapping Issue

Hello, I have a problem with domain mapping. My website has 3 domains now.
I've created 2 subdomains (a.e. subdomain.mastersite.com and subdomain2.mastersite.com, both has id's 2-3.), not subdirectories and configured them as it should be, via Domain settings. So now I can access every site with domain I have mapped, but when i try to log out, or to use any other wordpress built-in link (log in, register, log out, dashboard) it gives me not mapped link subdomain.mastersite.com instead of my mapped domain. Where is the problem?

I have regenerated .htaccess properly.
All definition in wp-config.php are good.
Plugins I'm using are WPMU Domain Mapping and Wordpress MU Domain Mapping

Thanks.
