At the moment Sibelius 7.1.3 has an anomalous situation where chord symbols (chord names) associated with a transposing instrument part ARE transposed with the transposing instrument part via "transposing score" However the associated concert (sounding) pitch fretted chord diagram is NOT transpose. This results in the weird phenomenon where the transposed chord symbol (chord name) does not match the fretted chord diagram
above the transposing instrument part . See attached example
As it is at times useful to have chords above transposing instrument parts, it would be a useful option if BOTH the chord symbol AND associated fretted chord diagrams stayed at concert pitch above the transposed part when using "transposing score"
