Bug: book titles in Lexham Septuagent don’t display with some fonts selected (ie charis SIL and others)

Summary of bug goes here. When using several of the default english fonts the greek title of books in the Lexham Septuagent display as blocks or not at all. If I select the section and copy and paste to another application (ie. Wordpad) the titles show up correctly in the pasted text. The heading also shows correctly in Logos is Arial or some of the other english fonts are selected (Charis SIL doesn’t work, Galatia SIL does)

Software version: 4.0c SR-2.
