That could have been the point, that they couldn't mute it! Perhaps they were faced with a choice, either record vocalisation and instrumentals from scratch, or leave it alone (or possibly even no choice, if the contract didn't allow them to record new instrumentals) – and keep in mind, that the vocalisations are also backed by the instruments, so it wouldn't be that simple to just mute that one part (or else you would get raw, unbacked vocalisations).
