Halion 4.5.1 CC mapper no effect - what's wrong?

Coming back to an earlier post for Halion 4.0.1 http://www.steinberg.net/forum/viewtopic.php?p=83922&sid=ee45a7b715d65f099421ddd30afd6cdc I’m not sure if I missed something to get cc mapper working or if there is in fact a bug. Attached is a short animated gif which shows the steps

  1. remote control of volume slider and pan slider works as expected by turing the knobs on Bome’s Keyboard drives the sliders in Halion 4.5.1 as expected.

  2. Now, CC Mapper Modul is added to the program as first modul and pan is assigned to volume - but turning the pan knob on the remote controller now does not drive the volume slider as assigned in CC Mapper.

Did I miss something?

Thanks for hints, tomotello
