Every night my Plesk installation at Strato seems to be "updated" to the same version

[Krumelur]

Every night at 01:19 I get an email that my Strato Plesk Installation was updated to 11.5.30. Is this a known bug? How to fix?
Here's the mail:

Parallels Panel wurde erfolgreich aktualisiert.
Die Liste mit den Änderungen finden Sie unter folgendem Link http://download1.parallels.com/Plesk/PP11/whatsnew-redirect.htm?platform=windows&locale=de-DE&version=11.5.30.

Diese Nachricht wurde automatisch vom Parallels Installationsprogramm versendet.

A minute later I then get:

Running task: C:\Program Files (x86)\Parallels\Plesk\admin\bin\php.exe -q -dauto_prepend_file="" -c php.ini "C:\Program Files (x86)\Parallels\Plesk\admin\plib\DailyMaintainance\script.php"

11.5.30 #25 and it says that it was installed 6, December 2013. But the last email is from last night and one every night before ever since I installed Pleask 4 weeks ago.
