Background music is adjusting behind narration
Hi.
I'm using Captivate 8 and have background music with narration. I've turned off the 'Adjust background audio volume on slides with audio' option, but on the first slide that has the background music, it's still very quiet until the narration has finished. It's fine on all the following slides with narration, but on the first one it begins really quietly, then suddenly jumps to the correct volume once the narration has finished.
The fade in and fade out is set to 0 seconds.
This doesn't occur when I open the project in Captivate 7 - only in Captivate 8.
Any thoughts on how to resolve this?
Here's a screenshot of my background audio settings:

Thanks.
