Adobe Captivate 6 Missing Audio Folder

I recorded audio to my Adobe Captivate 6 project, slide by slide.

I can see the audio on the bottom of the Timeline.

When I right click on the audio, it shows on the upper screen of the Library tab on the right side of my screen, but I do not see an Audio folder on the lower part of the Library screen like I usually do.

How do I see the Audio folder again?

Please advise.

Thanks,

Dave
