everkool82, this is to do with the Group Columns by Term feature that you can disable under Admin > School Admin > Markbook Settings, which was written into v12 by @skuipers (along with some other excellent changes to the Markbook). If you look at the settings you can see the scope of other changes. It is possible to use the Markbook with the new options off, in which case it is functionally like the v11 Markbook, but with some interface improvements. Ross
