Inventory / Software Summary - Depicting different versions

An issue has arisen in that we have just installed Symantec Antivirus version 10 around the network. This was upgraded from version 9.

In the inventory list, the version is added with the title "Symantec Antivirus Client" and therefore version 10 is being bundled into the inventory with version 9 - which is then making the license purchase against install population incorrect.

I note that in the Software Summary there is a version field underneath the product name, but how do we populate this and will it create a new instance of this software title in the inventory?

Please help - our planned roll-out for the symantec version 10 will happen this weekend!
