Trouble with animating from imported AI art boards

Hi all,

I'm trying to create a rolling head GIF in Animate. I designed the art work completely in AI and have imported the art boards. However, I can't seem to get it to work. I'm new to using Animate, so there's a bit of a curve for me. Below is a screen shot of my Animate files. Maybe someone has an idea on how to move forward. Thanks so much for your help.
