Recently added doesnt work for 3 albums

[sly]

3 specific albums  dont appear in ''Recently Added'
I added a different one from those 3  and it works.
Why these 3 albums dont appear in 'Recently Added'

edit the auto-playlist and click the "Exclude" button to see if the files are excluded

Those files have been deleted from the auto playlist results indeed!
I managed to include them, thanks for your help.
How did it happen?

[Steven]

it happened because you deleted them from the playlist
