MacBook wallpaper: Invisible photo won't delete

Hello, have you guys have ever experienced "ghost" wallpaper on MacBook? like not an actual ghost but the photo is invisible on the wallpaper section. you know on our general- wallpaper, we have one category that has the photo we've add as our wallpaper, I have this one photo that I try to delete but it still there cause its invisible and by invisble I meant, it looks like its not there but its actually there. I found out about it after set the shuffle system for my wallpaper that contains the photo I add before for my wallpaper and in the section, the photo isn't there but when you shuffle it, its there and you can't delete it, can you help me with this issue?
