I haven’t had any issues with phantom audio bleeding from other clips.
I’ve had luck using opt-2 to make my edits video only. I’ve also been able to go into the audio inspector and drag the volume of the clip down to zero, or deselect the audio checkboxes to turn off the tracks.
You can also break the clip apart into its components, then delete the audio tracks.
Actually now that I think about it, I DID have some strange audio, and I didn’t know where it was coming from.
I went through and soloed clips one-at-a-time until I found the errant clip, expanded the clip so I could see the audio, and saw that an audio clip had been extended.
If this is a bug, you should still be able to find a workaround to isolate that cough. There have been a few times where I’ve replaced a clip with itself, to reset a clip back to its original state.
Good luck.
