Check your attachments.

To see which video(s) an individual bumper is attached to, click the "Attachments" link. Look for a dotted number badge on the libraries listed under "My Subscriptions."

Click the badge and you'll see the list of videos in the library. The checked titles are the selected videos that are attached to your bumper.

Example: The image above shows the badge indicating a bumper is attached to two videos – one video in the Audiology library and one video in the Dermatology library.
