When doing a morph search for lemma:euaggelion OR lemma:euaggelizo in the Logos Septuagint with Logos Morphology, it does NOT return Psalm 95:2, whereas doing the same search in Septuagint SESB returns all the same verses as the Logos LXX as well as Psalm 95:2.
I looked at Psalm 95:2 in the Logos Septuagint with Logos Morphology and the verse is the same as in the SESB Septuagint, so the search should have returned it.
