Page Header Cover issue

My aim is for the post title to appear on top of a custom cover background.

I have the Page Header display setting for Single Post set to “Cover”, and also uploaded my custom background image in the Cover settings. The “Show Title” in the Cover settings is toggled on.

Under “Advanced” settings for Single Post Title & Tagline, 2 things can happen:
1) If I choose “Default” or “Use title & tagline from blog page, it will only show my custom background with no title on it.
2) If I choose “Use title & tagline of current post”, it will use my featured image as the background and add the title on top of it.

It doesn’t seem to pull the title with the default settings despite the instructions saying otherwise?
