[xwiki-users] strange notifications with watchlist application

Hello, Since I've migrated to 4.4.1, I've been receiving notification for these documents (about once per day): XWiki Wiki Component XWiki Class Wiki Component Dependency XWiki Class Wiki Component Implements Interface XWiki Class Wiki Component Method XWiki Class Translation Document Class UI Extension Class There is no author and no update in the notification It's really disturbing for standard users who received that too. There's something to do to avoid that? Thank you ncg
