Issue with track muting

I am having an issue when I solo a track. Each time I solo any track in my project, there is another specific track that will solo along with it automatically. When I try to press mute on this track, it will not let me and will remain soloed until I ‘unsolo’ the original track/s I was working on. The only way I’ve been able to mute the track is by turning off the ‘Read Automation’ button. I’ve searched for the problem and tried to look for anything atypical about this track to the others in my project but have found nothing useful. I’m guessing the fix is pretty simple, does anyone know of this issue?
