Template settings would be ignored after update to 2.0.22c

[marcoartwork]

I have running gavicks template "yourshop".
After updating to virtuemart 2.0.22c the Template Backend settings wont work in views category and detailspage and checkout pages.

The crazy thing is, all the other Pages like Home, Kontakt, are in the normal Layout - with template Backend settings work.

You can view the differences right here:
The correct displaying Layout

The failure view - Watch at the  MainMenu and the footer :
http://www.rcs-audio.com/v5/index.php/de/produkte/sprachalarmierung-en-54-16
in this Case all Backend template settings (like column widths, menu options) are ignored.

Does anyone have a idea where I need to modify or correct the code?

Set Default template and the Category Template to "Use joomla default" in Config/Templates.

To cope with the way that some commercial templates try to control layout a generic fix for this is now in VM2.0.22d
