Date format issue when I try to find the first occurrence of names with associated dates

I am working with two columns in Excel:

Column A: Contains names (e.g., Giovanni, Maria, Leo, etc.).

Column B: Contains dates (e.g., 01/2025, 06/2023, etc.), in the format DD.MM.YYYY (e.g., 29.10.2023).

I want to find the first time a name appears in Column A and retrieve the earliest date associated with that name from Column B. For that in Column C I used:

=TEXT(MINIFS(B:B;A:A;A2); "DD.MM.YYYY")

As result:

As you can see, there were issues with how Excel was handling the date format.

The date was displaying incorrectly, showing 23.01.YYYY instead of the actual year (e.g., 2021).

I am know due to formatting or Excel not recognizing the date properly.

What I have done so far was ensure the date format in Excel, but it didn't work.

Any suggestions?

My lenguage setting is norwegian. I had to change the formula to:

=TEXT(MINIFS(B:B;A:A;A2); "DD.MM.ÅÅÅÅ")
