Old shows without fixed ending date are disrupting Top Airing Shows list

Something went wrong with that feature and only first four entries are actually still airing (as seen here: http://mydramalist.com/shows/top?st=1). To makes things weirder, the list on the main page is different, it sticks to currently airing shows only, lacks Age of Youth 2, but shows Onna Joushu Naotora and some Chinese show that has zero ratings so far.
