Damian, that might be related to the wide gap you were reporting previously.
In the olden days I remember making spacers or putting washers under the flat of the hinges to avoid that problem. But of course, that makes the gap even wider. I would check the inner flange where the door-skin is crimped to the frame; there may be scope to dress that down or out a little to create clearance taking care not to spoil the lines.
If the door is a replacement, it's possible that the contours of the door and wing are slightly out. If that is the case you might be able to carefully re-shape the edge of the door or slightly tap in the edge of the wing.
