150: Bass clarinet - sounds at wrong pitch

Bass Clarinet in Bb (i.e. treble clef version) should sound down a 9th from written. It does, but when viewed as a non-transposing score it sounds down an 8ve, which should only be the case with 8ve transposing instruments such as Double Bass. Bass Clarinet [bass clef] should sound down a 2nd from written; currently sounds down a 9th.

This has been addressed in subsequent versions of Sibelius.
