Voice 1-4 toggles disappear if more than 2 voices are shown and the toolbar is on the side.

Sorry if this has been reported already. I like to have all 4 voice buttons shown on the toolbar because I write drum cues and such, and I noticed that if I place the toolbar on either the left or right side, the voice buttons disappear. They're there if only two voices are shown via toolbar customization, or if the toolbar is on the top or bottom. I took a screen recording but I can't upload it here.
