I know this was an issue when the new rating first came out, but her history still isn't right. Her foal Angelic Creation is WEE, not EEE https://horseeden.com/horse.php?id=17553851

The foal was born before the new rating came out and therefore will not be switched in the dams breeding history. This issue has been addressed several times and it has been said time and time again that there is no way to fix this and that it will not change. I think you just didn't realize the foal was born before the new rating was released :)
