Digital Art Zone

I had to remove some of my content so that I had more space on the comp to actually render something.  Unfortunately it left a place holder behind in the smart content.  Any ideas as to how I can get the smart content area to update so those are gone?

Right-click those items and select Remove Oprhaned References.

when I right click (I’m using 4.5) I get Explore Product Contents

You need to find them in the Content Library categories and “Remove Orphaned References” there.
