Octave types in the Lines dialog missing

As you can see, the dialog just shows a bunch of 8--- without showing the type of octave (8va, 8vb, 15ma, etc). But when you mouse over, you see a tooltip with the octave type. Please don't tell me this is by design too. Also, direction nub is gone as well, and whatever you do select displays incorrectly. For example, select a range of notes, and select (after hunting for and eventually finding) 8vb. An octave line will display for octave above, not below.
