While my readjustment was for the outer door you may want to consider the same approach. Cut a piece of wood to match the contour of the door frame. Then you will have to add thin slices of wood one by one and clamp. repeating this addition till the door matches the frame. You have to OVER BEND the door in order to move it to the correct form. When adding each slice of wood you have to plane them to give a smooth curve leaving the high spot where you wan the greatest bending.
Note the original dark board and the additional thin slices of lighter wood with the high spot about at the door latch.
This is an early picture in the process. I had to add several additional 1/4 in. pieces to get the final curvature.
