I am using the XOOPS news module: version 1.6.1
Xoops version: 2.0.13a JP

The "archive articles" in the news module disappear when an article is expired.

So the current articles will show when looking in the archive of this month:
http://www.kobeclub.org/modules/news/archive.php?year=2008&month=7

The previous months show: "There are 0 article(s) in total"
http://www.kobeclub.org/modules/news/archive.php?year=2008&month=5

I have been searching a long time, but have not found any clues.

Looking forward to some help.
