Downloaded issues not in Newsstand

I am a print subscriber and the first issue I downloaded went onto my newsstand, so I could read it offline, ( like on an airplane). But while my subsequent downloads are accessible while I am online,they are not on the newsstand and I cannot get to them unless I am online. But they take up space on my iPad . I have auto delete turned off because I want to reference several months. Either the app is broken or you only have one on the newsstand at a time. Either way, this is pretty lame.
