The Recently the album is a generated view of all photos and videos from each Date added to the library.
This is in contrast to All photos views that are always in date captured order.
For example, if someone uses AirDrop to send you a photo they took on their phone, the photo will appear at the bottom of News, but in the correct data position for when it was taken in All Photos.
This cannot be customized. Usually use the All Images view, unless you are specifically looking for media when it was transferred.
