Can't record in Adobe Audition waveform, but CAN in multitrack

On the latest Adobe Audition from CC, connected input and output to Focusrite Solo Mk 4 in device settings, ASIO etc, all fine, but in waveform after starting a new file, the green level bar shows input but there is no waveform displayed.  After "recording" the waveform is a straight line.  However in Multitrack by arming the track by clicking R etc it works fine, recording a waveform, that on double clicking opens in Waveform view.  But I can't record in waveform view at all.  Any ideas please?  It would be highly appreciated. Thank you.
