[SOLVED] Cubase Inputs List Only 9 of VEPro's 18 MIDI Ports

[Solved, ports show in Mixer, just not in Track Inspector for some reason.]

VSL user here.

Trying for the first time to combine all orchestral instruments into a single VE Pro instance. In order to accommodate this I have increased my MIDI ports per VE Pro instance from 8 to 18.

But when for Cubase MIDI tracks I go to assign MIDI ports from the dropdown list, it only lists 9 MIDI ports.

Not sure whether this is a Cubase limitation or there is some way to show all available MIDI ports.
