As title states i think the drawer division FF formula is wrong. If I leave it set to defaults, the division is placed behind the frame as expected but finishes to to the back of the backboard. In the picture, on the left division is my setup and on the right is default. Note if i try to dado into the backboard, it no longer drills holes, if i set flush forward to the backboard as per picture, it drills holes. This I'm fine with but would rather the dado as per rest of construction. 

If I cut it all at the default drawing the drawer division pieces would all be too long.
