I have noticed that whenever I use Copy Bible Verse to copy Hebrew text to any word processor (Word and Pages, primarily) if an atnach accent appears underneath an aleph (א), especially when the vowel is qametz, in the Hebrew text (I tried with BHS/WHM, BHS SESB 2.0 and LHB) it appears instead as a double qametz . Cf. below/attached. This is a screenshot comparison of the same text, one is within Logos resource and the other is from Copy Bible Verse.
