Photos from iCloud

Hi guys

whenev my phone was low on storage I would store my photos on iCloud and remove them on my phone. But today when I check my iCloud photos they are gone. I have 92 photos on my photos and on iCloud it says 223 photos yet ‘restoring from iCloud photos ‘ in my library says 323 photos. How can I restore the lost photos on my iCloud ? And when it says “restoring from iCloud” does it mean it will restore all my photos?

thanks in advance
