Cannot Select Additional Popup Options In Write Mode (Dorico 4)

This has already been reported so the Team knows of it.

Cannot click on the icon flyouts in the left panel

I am trying to select one of the 4 insert modes. I can right-click on the insert button and it displays the flyout of the 4 mode buttons, but when I click on any of them, the flyout disappears and the first mode remains in effect. This is true for all the buttons that have flyouts (create voice, dotted notes, tuplets, grace notes) Any idea what I might be doing wrong? I have Windows 10. I can set the modes through the Write menu.
