I’d like to tell you that you’re right, but it is not true. We haven’t any customization on the Basel web site that hide the title in some other method.

The phrase “You are currently editing the page that shows your latest post” in your screenshot means that you did a test with selected the blog page in General -> Reading. On our Basel installation we have deselected that option. Just as you suggested to us also before. In fact only in this way it is possible to customize the body. In our Basel installation disabling the title on blog theme preferences, the titles does not appear also in category pages.

On Woodmart there is some bug between the option that disable the title on each blog page and the header customizer. Because if you remember well, I showed you like there was something wrong with the overlay of the body on the header.

If you would like really to fix this bug you could do that. But you simply do not want… and it is really frustrating for us, because we spent money for your theme and your support 🤷🏻‍♂️
