Hi @Mairi38
You don't really change the year, you click the radio button to "year" then hit apply. You'll see a scroll bar to the right. Scroll all the way up to the top. You should see January 2022.
For Reservations, go to your list and highlight "Completed". Then click Check-in Date and you'll see a little down arrow. That will change the reservations to start at your oldest and go forward. Click again, and it will revert to newest to oldest.
Hope it works!
