Hi, I have a pupil who has changed classes and has the orange lines in the correct places. However. the pupil was temporarily placed in the middle class (forced in by adding scheme) and whilst it looks like they are not there, they are appearing on all the marksheets of this class (along with top class). How do I delete them from the middle class entirely? I am unable to change any dates when I click in the middle box. Many thanks.
