Upgrade Notification for Plugins Showing Incorrect upgrade information

The Plugin Admin page in WordPress 2.5.1 (and 2.6) is showing that there are upgrades available for 2 of my plugins (AWSOM Archive and AWSOM Uninstaller), when in fact there aren’t any upgrades for these plugins. It is actually providing links to a different plugin, AWSOM News Announcement, as the upgrade. Where is WordPress pulling this from? The SVN archive? How can I get this fixed so that people do not get these erroneous upgrade notifications? The major issue that can occur is if they try to do an automatic upgrade it will probably screw up both plugins.
