CST Studio Suite Copy Issue

Hi,

I was working on the final design project for my class. One of the steps requires that I copy a few components from one design to another. The issue I have been having is that when I try to copy by right clicking the option is greyed out. Does anyone know if there is a way to fix this?

I have tried using Ctrl+C and restarting the application.
