Audio problem: When Maria is talking to the other woman at the ruins after she comes to, the last time she says, "Our friends," her lips don't match the words.
Audio problem: When the Germans are banging on the bunker door with sledgehammers the clanking sound always happens when the hammers are not hitting the door.
Audio problem: Right before the escape from the fortress, Miller throws his gun from the cliff into the water with the 'splash' sound following rather quickly afterwards. When they climb down the rope and jump in, it takes a lot longer for them to splash into the water.
Audio problem: At the end when they're on the small getaway boat, Irene Papas asks Anthony Quinn a question. He answers, "Yes," but his lips don't move.
Suggested correction: She is probably able to write.
This correction is too speculative and offers no in-film evidence or further proof.

Anna was a school teacher.
Wasn't she a school teacher? So probably could write.
If she "wrote" about the scars wouldn't someone want to see them, perhaps get her to a doctor? Making up silly, deux ex machina explanations for film mistakes does not invalidate them.
Your assuming a lot like when the Germans release here. She could have "recovered" and had a fit anytime anyone touched her.
As was noted above, making up silly, deux ex machina explanations for film mistakes does not invalidate them. You cannot 'recover' from scars. It is ridiculous to think that nobody ever thought to get Anna to a doctor for treatment.
