Why did the audio from my video file with overlaid title disappear when I imported it into Pinnacle Avid Studio PC

This information applies to Pinnacle /Avid Studio which runs on iOS.

Pinnacle / Avid Studio PC doesn't support the audio from a video file in the background of a title. You can re-import the media into the background of your title, or to a different track to use its audio from with Pinnacle / Avid Studio PC.
