My wallpapers always zoom

Hey! I am trying to set an album to be my wallpaper but it zooms in every photo and I can’t pinch to zoom out, it just stays as is.

I have cropped the photos to be ‘wallpaper size’, I’ve tried screenshotting them but nothing is working!

Any ideas would be super appreciated :)

(I have an iPhone SE(2020) and it is fully updated to the latest iOS)
