My daily digest does not show any tags

Hi, I have a lot of exams these days and preperation for an abraod year. So I created tags like @school, @abroadprep...
I still also use @todo and @done. My problem I customite my daily digest so it would show me those items to but I do not see them. The "folders" are there but empty. If I check my items they are all properly tagged. Strange all things show up at the calender part...any ideas about that. It would be nice if I can see it sorted again since only calender view is quite time consuming to read. Any ideas about that
