Guitar and bass guitar don't get transposed when enabling "Concert Pitch".
1) Create new document with a guitar or bass guitar staff (or choose one from a template or pull the treble or bass clef 8va bassa from the palette.)
2) Enter some notes.
3) Press the "Concert Pitch" button.
When enabling Concert Pitch, all the notes should get transposed down an octave for guitar and bass guitar staff, but this is not happening. Also, the number 8 below the clef for guitars and bass guitars should be visible and only hidden in concert pitch mode.
When you pull the guitar or bass guitar clef from the palette, the 8 below the clef doesn't get hidden when enabling the Concert Pitch button.
These issues are present in the templates that include these instruments as well.
Lastly, just for the record, this behavior is not new to version 3.3, it's been present in previous versions as well, but I guess it hasn't been reported.
