I do not think you will have any problem. If asked, just explain that you only requested UDU. Supported upgrades have to be supported at the time of request, and you did not request a supported upgrade.
This may actually be my sit. No one is in 1st both ways but E and E+ are pretty much fully booked.
I think I may just take my chances. Its a vacation if I get to the airport and have to straighten this out I have all day to deal with it if I need to. Worst case I have them pull the miles from my account. No biggie either way.
