Problem with new Ambisonics Channels

Generall the N8.2 update is fantastic - works very smooth here. But I have one problem with the new Ambisonics channels. Using an Ambisonic Group channel I tried to pan a stereo source. The source channel and the Group channel mute everything, there is also no level meter running anymore. I have the Noisemakers Ambi Bundle HD here and SSA a1Panner - I get everytime totally silent channels, no matter if I use 1st order or 2nd order channels. Any ideas?
I’m on macOS Sierra with a Mac Pro and RME audio cards.

While you’re waiting for Noise Makers and SSA to update their plug-ins, you can use the IEM plug-ins: complete set including panners and a very good decoder.
