For example, Tower of God, which has a lot of languages but only English appears for the chapters and not the other languages which in my case is Spanish.
The language filter is site-wide. No matter where you set it, it's the same one.
It doesn't seem to work since the only language being displayed is English and I already set it so that English and Spanish are the only ones to shows.
In your follow list, right-hand side above the RSS feed, there should be a language setting option. You can set it to follow all or follow selected languages.
Yes, I know about that part thanks, but sometimes there are mangas that doesn't have all chapters in English and they do in other languages and that's my problem.
