Crossbow Expert Feat... for Spells? was marked correctly as a duplicate of Does Crossbow Expert's point-blank attack benefit apply to all ranged attacks?.
However, the latter only has one positive answer which has only one sentence and no citations. The answers on the first question both have at least official support. (Full disclosure: one of them is mine if it matters at all.)
It seems to me that it would only be an improvement to switch around the duplicate marking in this case or to merge the Q&As.
