I am puzzled as to why there is an entry on the right side (Concordance section) (a) with no highlighting to show to what it applies and (b) with no corresponding entry on the left side (Hebrew Cantillation Interactive).
The cantillation data is tagged on text that is not translated by your preferred English translation. Try searching for the following in a Hebrew Bible (restrict it to Gen 1:1 if you want): {Label Cantillation WHERE Name ~ "Merkha" AND Type ~ "Conjunctive"}
That explains why it doesn't appear on the English/Guide section. But why doesn't it appear in the Hebrew Cantillation Interactive?
