Certain audio tracks playing back softly even after theyve been deleted

Hi has anyone had this problem. I'm using Windows 10 ruing Studio one 3 pro. Havent had any issues with this until now.

When I delete certain vocal audio tracks some of them seem to continue to playback as if they haven't been deleted. They playback usually a lot quieter but still very much there in the mix. Ive pulled all fx and buss aux off, restarted etc. There still there.

Any help would be huge!!
