Installed fonts missing in layout mac

Layout 2019.2 keeps refusing to add installed fonts to the fontlist. When updating a set of Ubuntu with bold for example, through a workaround (choose medium > rightclick-bold) it works, but after saving the settings are gone, because the fonts will not show up.
IS it me or is it a bug.?

I started off by wondering how you are using LayOut under Linux, but then realized that Ubuntu may be a font name in this case.

The font, from this page:

works for me. Including Bold, and it shows up in LayOut right away.
