Whenever I change between guild settings and manual, I get the following error popup. I am also unable to save a new configuration screen, even if I delete the old one from the guild info (I'm the GM).

Message: Interface\FrameXML\StaticPopup.lua:4899: Usage: PlaySound(soundKitID, optional["SFX","Music","Ambience", "Dialog" or "Master"], [forceNoDuplicates, runFinishCallback])
