Troubleshoot volume change in AE

Question

Hi there, I have a 24bit/48k .wav audio file (music) that I've been using for years in Premiere.

I've just started some social ads in AE but whenever the audio is in certain Comps, it jumps in volume by about 5db at around 7seconds - this volume change also renders in final renders.

In the Comps in question, there are no keyframes or effects on the audio file, nor keyframes on any other layer at that point. I've removed and re-added to the comp, purging Memory & Cache, and restarting AE. But no joy.

If I add to a new comp, there's no volume change so clearly something is causing this - does anyone know how to it track down? Have never seen this before.

Any help much appreciated. Cheers, Ben

OK, found the issue.

The video layer above, somehow has a copy of the music starting at the 7sec mark - have I somehow recorded a copy of the audio into the other video layer?

I haven't seen this before - is there a shortcut I accidentally hit maybe?
