I'm in Logos Bible Software 6.0 (6.0.0.3700) (Update channel: beta). Also Win 8.1.
I selected 2 Chronicles 35:18 in my ESV, then the word "Passover" as its lemma, and selected Visual Copy.
One of the slides seems fine. In the other, the accented transliteration is twice replaced with the blank rectangles, as if the font set can't do as requested.
