New assets have been shared but aren't showing up in illustrator library

Just getting started using shared CC assets. I can see and use the first batch of imaged shared with me just fine in my library in Illustrator.

Recently a second batch of images was added to the shared CC folder, but only the first batch of images is visible in my library in Illustrator, not the second batch. When I click on the CC button in the bottom corner of the libraries window it says "all libraries are up to date." What am I missing?
