Typography Bold missing

Hello,

i just create a new website using Skyline WP Hero Layout.

There is a auto created Menu.

I can`t set the Menu in bold letters.
Bold is completely missing in the typography settings. Only Normal and Italic is possible.

In text areas it is possible with “strg+b” to use bold text. You can save it publish it and it will be saved.

But the main menu doesn´t react to “strg+b” cause it is a automatic menu.

Is there a possibility to make it bold? The only thing i´m thinking of is an self made menu with a text area and hyperlinks to the sections the menu normally reaches.

Any Ideas?

Kind regards

Georg
