Received a seconf A-number in AOS receipts

[Houston2018 0]

Received a different A-number (second A-number) in my AOS application receipt. My earlier A-number was different in F1 EAD card, etc.

1) Is it an issue to me or my application process that I need to notify USCIS?

2) Will it get corrected by USCIS in due course? If yes, then when?

Thanks for sharing experience / knowledge.
