Why when I change specific fonts in TB then the highlight font options is already disabled? The problem is that when I will leave the font as default which is BBMillbankTall in some functions this font is replaced by the default font set by the phone's user and in some cases it's blocked as this font. And this font it's not nice. When I will change it the highlight option(white) is disabled and when I have dark banner the text is barely seen because it stays black:/

If you are talking about os7, that seems to be the rule. Be careful what font you change, some font changes make the theme not function properly.
