Libre not showing font in Character Menu List

I just purchased, downloaded and installed the following fonts:

  • Optima® Std Demi Bold (OTF)
  • Optima® Std Medium (OTF)

I used Apple Font Book to install both fonts:

I can select and use the fonts in Photoshop and TextEdit:

But in Libre Office I don’t see the Medium font and instead see a “Bold Italic” version of the Demifont - which I don’t believe is part of the package of fonts I purchased and don’t recognize it as having been an option before:

Can you think of any trouble shooting efforts that may solve this issue? I restarted the computer and apps - no change.

I’m using an Apple MBP, Mohave 10.14.6, Libre Office 6.2.7.1
