Glove Box Adjustment

My glove box keeps springing open (which is getting annoying). I think the lid might have moved slightly so that the lock isn't engaging fully in the slot to hold it in place.

Does anyone know how to adjust the lid position? I've had a look at it and there doesn't seem a way that is apparent.

The picture shows how it protrudes above the dashboard.

Check the plastic hinge isn't cracked allowing movement.
