Due to a manufacturing error a batch of our front wood flaps, part 4E, the screw guide is placed at a slightly lower position than designed. This can result in the latch not aligning with the lock correctly and can prevent the box from locking.
If you are up for a challenge, this can be solved by either using a push-pin/needle or another sharp object to replace the holes in the correct position.
