Joomla 4.1.5, Template "Dylan" . In "Systems" > "Site Template Styles" > "Dylan - Default" > "Template Options" > "Typography" I defined the headings as I wanted to. I activated Heading 5 and Heading 6 (as they were deactivated). But Heading 6 is not doing what I expect. the definition of font (Verdana) / colour (1.1em) / size (a shade of green) .... is simply ignored.

Heading 5 is fine.

And one more thing: While Heading 1 to 5 show correctly on the desktop, numbers incuded in the heading will NOT have its defined colour on a Mobile phone. It does sound weird, doesn't it? Where did I go wrong?
