Unison notes won't adjust

mscoreNightly-r4674

Windows 7

Open MuseScore
Select Drum kit
Enter two drums that appear on the same note (e.g. both on E if it's a bass clef).

BUG - the notes both still appear on the same side of the stem.
When I click on note properties to adjust this nothing happens.

See .doc file with pictures to further explain. This scenario does come up a lot in drum notation (in my experience).

Thanks,

Stu
