Chord track can not show chord in the track

Chord track can not show chord in the track ,Chords can shows in the chord editor, but in the chord track ,it just a X chord symbol .

The problem shows in Cubase 10.5.2 ,and it is ok when i downgrade to 10.0.6.

Ok…i know the reason,

there is a function called in control with my novation launckey , and i did the wrong settings in cubase
'midi port settings ’ I ticketed the ‘ALL MIDI’ option ,so there is a constantly c-2 note in piano roll .so this affects the chord track.
