Windows 10: Lock Screen image not showing on Login Screen

When I lock my pc, the Lock Screen displays my custom image and the time/date etc. However when I press space to enter my PIN. The image disappears and there is just a blue background. I also noticed that I don't have the 'Show Lock Screen background picture on Login Screen option' as seen below. How can I fix this?

Lock vs Login screen screenshot

You can use your own image of any background and just go to settings/personalize/lock screen and click on browse as in the image below. It should make whatever picture you use as the Lock Screen

 

different lock screen and sign in screen?

Step 2b is labeled as Change the Login Screen Image, but the steps show you how to change the Lock Screen image. Step 2a is irrelevant. It only tells you how to change the desktop background.

What I want to do:
Set Spotlight as the LOCK Screen Image(s) - Done
Set the Win 10 Hero Image as the SIGN IN Screen Image - This is the one that shows after you click on the lock screen and you are able to type your password. If I uncheck "Show Lock Screen Image on Sign In Screen", it shows a solid blue background behind my Password box and user image. This is what I want to change to the Hero Image....

 

Login Screen Background keeps defaulting to stock image

I've set a custom image on my lock screen to show up on the initial login screen whenever I first start up my computer. But occasionally, the login screen defaults to a stock landscape image that comes with Windows 10.

To clarify, here are the steps I've taken:

• Go into Settings -> Personalization -> Lock Screen
• EDIT: Set image to Picture
• Click Browse... to look for and select a picture
• Turn on Show lock screen background picture on the sign-in screen.

However, no matter how many times I retake these steps, the default login screen background occasionally
comes back. How do I stop this from happening?

UPDATE: I forgot to mention a step here in my initial post. I have already set the background to
Picture, thus the custom image.
