Character Assets downloaded do not appear in Media Assets (Captivate 2017)

I just upgraded to Captivate 2017 and I am trying to download character assets.  When I click to download, I get a message saying that the character has been successfully downloaded, and the .png file is in my Documents Library under eLearning Assets/Characters_10_0/Assets.  However, when I click on Media > Assets, they are not there (i.e. Carrie, below)  Kate worked, but not Carrie?  Thoughts?
