Midi Track Inspector - VSTi Output selector gone?

In the inspector of a midi track, which is connected to a vsti with multiple outputs, the selector to change the output audio channel seems to be missing.

I made this cubase 7/8 comparison screenshot.

Cubase 8.0.40 / Cubase 8.5.20

(Tried to post this in the issues subsection without success)

Its a mac only problem, VSTi outputs are active
