Shopper Group - Sort and Default Icon Defects

[largue]

Hi there

I am currently implementing a Joomla/Virtuemart solution and believe that I may have uncovered two potential bugs.  My system is specified as follows:

Database Version: 5.1.65-cll
PHP Version: 5.3.17
Joomla Version: 2.5.8
Virtuemart Version: 2.0.14
User Agent: Chrome - 23.0.1271.64 m

Defect 1:The Default Icon in the Default Shopper Group references a nonexistent directory in the Shopper Group - Edit view - administrator/templates/khepri/images/menu/icon-16-default.png - khepri is the problem.
Defect 2: When clicking on the Id column header in the Shopper Group - List view, instead of changing the sort order to ascending or descending, it removes the Default setting so that no group is assigned as the default.  The message returned on click is 'Default shopper group changed'.  I currently have three shopper groups - Anonymous, Registered and Prestige - Registered should be the default.

Michael
