Avid Control - instrument plugin channels as inputs can't be selected

[basehead617]

PT 2019.12

- Create Instrument Track with e.g. Omnisphere

- Create stereo Audio Track

- on Avid Control go to 'Input' for the Audio Track channel and click 'no input' to select it. You can change the input to a physical input or to a bus but the 'plug in' slider doesn't have any effect and doesn't show any available plugin channels (for example Omnisphere's Stereo B through H). The 'IN' LEDs in the app for the hardware input and bus seem to act oddly too (both staying on in some cases for example or becoming non functional)

- The above works in the PT GUI itself and shows all the available plugin bus choices

Anybody else seeing this?
