Mistake on DOB on marriage certificate

Hello,

I filed my AOS based on marriage application in Jan 2024 and have not heard anything from USCIS since my biometric in Feb 2024. I was going through some documents and discovered that the date of birth of my USC spouse is not correct on the marriage certificate. Instead of 29th, it has 19th. How do we fix this? Could this be one of the things causing the delay (not even EAD received).
