Graphics applied to model automatically scaling to model dimensions.

Hello, 
I'm having a recurring issue within Dimension where when I apply a graphic to an object that has already been resized, the graphic is automatically taking on the same scaled proportions. For example, I'm working on a project where I need a rectangular box, so I scaled the cube to meet the dimensions needed. When I go to apply the logo graphic to the box, the logo is stretched and appears to be taking on the same proportions to the box which is less than ideal. 

Has anyone encountered this issue and found a solution? Thanks in advance!
