There ia nothing worse than the feeling that comes over you,when you realize this kind of boo boo has been made...the whoosh as it hits the brain is torture....
Once a few years back, when I was sailing on the Gem for Cruisemates...the paper work that was sent for me, and it had the wrong date...reading it, that way, meant that I mised the ship by a day
I was panicked, to the nth degree! Luckily in my case, it was their boo boo,..
I hope it all works out for you.
