Extended wallpaper won’t go away

I’m trying to put a photo of my fiancé and I as my wallpaper but in the top left-hand corner it’s all blurry. Anytime I hit the extended wallpaper checkmark to make it go away. It just zooms in on us but anytime I zoom out it still has that blur effect. (No matter how much I blur out it’s still there) How do I make this go away and just use the standard wallpaper. If you move to the second slide, you will be able to see there’s plenty of room to fit. Any help would be great
