They've sent things out in error before. I got one like this two years ago, sent to our CEO. Got things all stirred up here, but we ended up finding out that it was an error on their part and they actually did have our submission.
If you have the confirmation of receipt of your edit report, send it in to them and request verification on what they're looking for. Or give them a call if you can.
