article order on current issue page

When I add articles to an issue, they are listed with the latest post at the bottom of the page and oldest article at top. They are assigned numbers and the “next article” “previous article” tabs navigate them properly, but they are just inverted in the list view. How can I change this behavior (I am a wp newbie)? Thanks in advance. I love this plugin.
