C10 variaudio

When I double click an audio track all that happens is that the sample editor window opens, but there is no variaudio option anywhere, either in the lower panel that opens the audio editor or in the main window inspector. How do I get the double click to give me variaudio options please? I cant see an obvious entry in the preferences or anywhere else. I’m on a fully up to date C10 version. It USED to work mok but has stopped giving me any variaudio options. Even earlier projects with tracks already processed in variaudio only give me the adjusted files, with no live adjustment options (the little boxes around the waveforms)

make the variaudio tab visible in the inspector…?
