Got NOA's for AOS application from K1 but confused

[adityaag 15]

We filed our AOS application combined (I131 and 485 along with EAD/AP) a few weeks ago.  We just got the physical NOA's (4 of them, one for each application) and are confused by a few things:
1. The case is still not trackable online.. is that normal?  The receipt numbers all start with 'MSC'

2. The Alient number for my wife is different than on the form that what we thought was her alien number.  We based it off the USCIS# from a previous EAD she's had.  Literally every document we submitted had the alien number thought but the one on the receipt is not it at all.  Is that a cause for concern or did the USCIS just update her application?

3. None of the receipts actually have a 'Notice Date' or a 'Received Date' filled in.  The I131 and I485 have a priority date which is good but that's the only dates I see on any of the application.

 

That's all I've got.. thanks in advance for any help.

1. Yes, it can take some time. If you are concerned you can call them.

2. According to uscis.gov:

USCIS Number

A nine-digit number listed on the front of Permanent Resident Cards (Form I-551) issued after May 10, 2010 that is the same as the Alien number.  The A-number can also be found on the back of these Permanent Resident Cards (Form I-551).
