Cannot access Edit Interface Settings dialog box in Windows

The manual says to double-click an interface in the Capture Options box to bring up the Edit Interface Settings box, but when I do that nothing happens. I am running WireShark 2.2.5 on Windows 10 Home Edition. (On a side note, it's pretty lame that the only way to access it is through double-clicking, without any fallbacks like right-clicking or a keyboard shortcut.) I am trying to turn on monitor mode so that I can monitor other machines on my wireless network (I have installed Npcap for that purpose), so I really need to access that dialog box or the whole effort to setup these programs has been pointless.
