This is very interesting to me!! I just quilted one for a customer on my LA and saw those exact errors when I was halfway through quilting it and I had to just finish it. I wasn't familiar with the quilt and hadn't noticed it before. It seemed to me like it was going to throw off the way the quilt should look. Told the shop owner and she just figured one of her girls had made the mistake when assembling it. She has told me that it doesn't stand out when you see it up on the wall. I haven't been to see it yet. It would make me sick if I had made it and not been able to fix it and to think it is a pattern error is sad indeed. Hope you take the time to tear and correct as it is a beautiful quilt! Good Luck.
