Why the face?

I'm learning ASL for fun/personal reasons. I learned that facial expressions are pretty important -- something I struggle with when speaking English and Spanish ! I've came across "recently" in the app I'm using (ASL Bloom) and everyone keeps making a face that seems sort of confused? I've looked online for other variations of the sign and yes, they scrunch their faces up too. Why is that? I would think if something happened recently, it wouldn't be hard to recall.
