You should call IIE, in my opinion, and ask about your application. If there was a mistake, regardless of whether it can be fixed now, IIE should be aware so it doesn't happen to someone else in the future. Plus, if there wasn't a mistake, I'm sure it would give you peace of mind to know that your application at least made it to the UK committee and was considered. Just my perspective, its up to you of course and I don't want to intrude- but it seems like you have a legitimate concern to raise given that no one else in the forum has mentioned being in a similar situation.
