What does this icon mean?

This icon appears on the very first clip in my timeline. Not seeing it anywhere else. When I click the icon that's on the clip it brings up a dialogue box with "duplicate" and "done" buttons. No clue what it's for.

Here's a link to a higher resolution version of the image.

It's a clip part of an audition.
