Story of the flights by registration or flight number

[Stefano BZ]

Hi
I saw today that the chronistory of the flights made that I can check from the database, with the reg of the plane and the flight number, is now reduced to just 1 week in the past, and not to 1 month as it was a few days ago.
Why? Is it not possible to see 1 month as before or at least 2 weeks?

Thanks in advance.
Stefano
