Log-in Screen Image Won't Stay Set Properly

Hi,
I'm having an issue with the image on the sign-in screen displaying properly, I'm currently running Version 21H1, Build 19043.899, Windows Feature Experience Pack 120.2212.3030.0. I go into the settings area and choose the image that I desire to see on my lockscreen, I currently have the box that says display lockscreen image on my sign-in screen checked. For some reason on the computer I'm typing this post on the 'selected' image fails to display & instead a different image that I really don't like displays. I have a different computer that's running the exact same version of windows 10 it all of my images get displayed properly. I'm to the point that I really don't know what to do next, in file explorer I have the settings set to show all of the 'hidden' settings that normally can't be seen. I know that there MUST be a way to correct my issue, but so far I haven't been able find it yet.

Hello David,

Just to verify, do you have Show lock screen background picture on the sign-in screen turned on below?

Show Lock Screen Background on Sign-in Screen in Windows 10

If so, see if you can post some screenshots of your related settings and your sign-in screen to see if anything may stand out.

As a test, does this still happen if you use one of the default pictures for the lock screen background instead of a custom picture at some other location?

Is this happening on the Sign-in screen at startup, after locking (Win+L) the computer, or both?

If you can take a screenshot of the Sign-in screen (phone cam if needed) and your lock screen settings and post them here, it may help if anything stands out from them.
