Newbie question - one clip of audio track looks smaller

[KateFreeland]

One clip in my audio track appears different. I have no idea what I did. Surely there’s an easy fix?
Thanks!

Here’s a better screenshot. The track in the middle is the one I’d like help with.
Thanks so much for your patience!
