Adding an SSD to a PC in Inventory

G'Day Lads (and Lasses),

I'd like to add an SSD to a PC in my inventory but when I click the Add Solid State Drive link, I receive "We're sorry, but we ran into an issue trying to get SSD data for the CDM DQ67SW-R01: No products found"

I installed a SanDisk Extreme 2.5" 120GB SSD SATA3 before I deployed the PC a few months ago. PC was not in service prior to SSD being installed (fresh hardware).

PC:
Core i7-2600
Windows 8 64bit
Spiceworks Agent installed

Any Ideas on how I can get this working?
