Servers showing as Workstations in IT Assets?

Hi,

I've been having an ongoing problem with regards to Servers showing as Workstations in the Assets menu.

Specifically, I have a series of servers that I want to show as "Server". I've gone into the Admin > Product menu and changed the classification for each to be a server. I've also changed the name of the product to begin with the word "Server".
The items now show in the server category, however they also continue to be shown as a Workstation as well.

I've noticed a few other people have had similar issues so I'm hopeful there's a solution to this (I haven't seen one so far). This is a very frustrating issue for me at the moment because we're trying to clean up our Assets in order to complete a compliancy project. If I can't see an accurrate count of assets showing in the proper category, it makes my job very difficult.

Thanks for your help,
