Mine have been that way for 10 years.
After lubrication the latches, I actually cut some shims out of thin aluminum and spaced the latch aluminum catch blocks out a bit but not too much. This helped some.
My tried and true method is to shut (slam) the door, visual both ends and if one door side is not latched, it will stick out a bit. Take your leg and lean against the bottom angle portion of the door and push and it will latch shut. You can hear it click. This works well (but you could get your leg or pants dirty!).
