Can't setup Atmos [solved, bug?]

hey all,
I’d apreciate help in setting up Atmos. I do not see the error here. I tried to setup Atmos using the ADM authoring wizard as well as manually using the online help guide.
Audio buffer size on 1024 or 512 with 48 KHz.
Still the render reports this issue:


my CR:

The ADM Autoring wizard is all green

I like to mix binaural - what do I miss here?

I found the issue.
I had to switch the project from 48 to 96 and back to 48KHz to be recognized.
Maybe a bug?
