In that case I have found your problem (T400CN). This is a chromogene B&W film which needs another pre calibration. You can find it in the menu under films and due to the (density) orange mask and so the (iso) speed you have used it (low 50-200, medium 200-400, high 400-800) Split Grade will adapt the densiometric curve of the film.
V2.2 and V2.3 I am sure it is in.
If you select this in your menu, split grade will print 95% OK with these films. Small adaptations you can make in the offset menu.
