Ultimate Branding does not hide all the links

I activated Ultimate Branding across the network, I customized the settings and disabled several elements for all users except Administrator. However, the first links (the icon of wordpress with the various links, "my sites" and list of sites), are still visible to users. Only on the main site (domain.it) all the links are disappeared, but in other blogs the links are still visible (domain.it/A, domain.it/B, etc...)

How can I do?
