Tagline won’t show when it’s check off to show

Hi,
Out of the box all works well and looks good. All plain and simple.
It showed on previous old theme and others I tried out.

When I do an inspect, it shows in the markup stuff, and is suppose to be white on black, but nothing is displaying. Tried highlighting to check, but it’s not there.

Thanks for letting me know what might cause that. Nice plain reversed theme – they are VERY rare now without all the garbage and millions of photo areas.
