Shopping Cart module assignment

[kbo]

Hello all,
When the shopper adds product to the cart, the shopping cart shows up with wrong menu.
I have Menu-1 for Joomla pages with assignment "On all pages except those selected" and Menu-2 for Virtuemart pages with assignment "Only on the pages selected" Both menus are complement each other.
So, after the shopper is moved to shopping cart, sees Menu-1 designed for Joomla pages instead of Menu-2 for VM pages.
I've made separate menu with shopping cart which shows the right Menu-2 after clicking, however it doesn't change the menu which can be seen after adding product to the cart.
I would appreciate any clue to solve this problem.

Joomla 2.5.8
VM 2.0.18a
