Packages Dimension Units not showing

[Tim Van Huis]

Hello,

I downloaded and am installing this extension today on our 1.8.0.0 development store.  In the Packages section, I enabled the dimensions, but there is no attribute showing for the Dimension Units - only the Weight Unit:

should it be there?  Thank you for any help in advance.

I'm having the same issue! No Length, Height, or Width attributes are not installing with Shipsync V5 on our CE 1.7.0.2
