Fly In Animation Not Repeating

Hi you guys,

I've had quite the day in Storyline today. Hoo boy. Maybe y'all can help me out.

I modified an existing file in which a menu flew in from the left when clicked. In the new file I created, the menu still flies in from the left. However, on subsequent hits of the menu button, the "Fly In" animation no longer is at work. Instead, the menu just appears.

Here is the original file with the modified version to follow.

I would appreciate any help. I have no hair left to pull out. LOL
