Mono events mute stereo events and vice versa in Nuendo

The same has been behaviour has been reported in the german forums in Cubase:

A workaround according to that thread is to convert everything to stereo…which is a workaround, but not a solution.

As others have problems with this too, i guess this is a bug.

Any comment if this is on the Cubase/Nuendo side or in Spectralayers, @Robin_Lobel?
(btw. tried 7.0.21, still the same)
