It's a rare day when we don't get someone with this query, you are not exactly alone. The main thread will tell you a lot more, but in essence it's not a big deal, just turn up at the normal time for check-in and it will sorted out in seconds there. Next time try using the direct Salesforce link rather than MMB, but it's now too late to do that. Hopefully this whole issue will go away in a few weeks.
