So I assume you filed online.
I also assume both of you are naturalizing under general provision (5 year rule).
If so, they are two separate cases. They may be treated by different officers on different days, and this is normal.
If you read N-400 form carefully, spouses' name and information section is not relevant for N-400 under general provision. It's relevant for people who're naturalizing under 3 year rule, based on marriage to US citizen.
When you file online, some sections are skipped automatically based on your case type.
Chill, everything looks good so far in your and your wife's cases.
Good luck!
