Staff type presets not available after changing instrument

1. Open attached score (produced in 1.3).
2. Right-click stave.
3. 'Stave Properties…'.
4. 'Change Instrument…'.
5. Choose 'Acoustic Guitar (nylon)'.
6. Click on the 'Type' box.

Result: Only 'Standard' is available.

Discussion: I would have expected the 10 other staff type presets to be in the list (after step 6, click 'OK' and go to 'Instruments...' to see what they are). Is this intentional?
