duplicate menuitem and other issues after VM2.0.2 installation

[alain.roger]

Hi,

today on local testing server, i installed VM2.0.2 on Joomla 2.5.2.
till now i only installed the standard package without AIO package.

Just after installation i went to component > virtuemart and I discovered that all menuitems of VM are twice :-(
i attached to this post 2 screenshot( 1 from installation and 1 for menuitem duplicity).

where is the problem ?
thank.
