MOD wheel does not work properly

HI There, I Have cubase pro 10.5
And I’m using my Yamaha MODX to play my MIDI Parts, And when I’m trying to record an automation track (by clicking on the little + sign on the lower part of the instrument track) Then finding the correct parameter That is going to be automated turning on read and write automation
press play and Then you should just be able to record your automation track right?

But nothing gets written,
If I open the vst and move the mod wheel the dynamics fader moves
and the sound changes but the automation will not be written.
unless I use my mouse to drag the dynamics fader up and down, but That is very very inaccurate
What to do?



Record the MIDI CC1 (Modulation) instead of Writing automation, please.
