[VST Transit] VST instrument rack settings not sent

Me and my friend are using the same Cubase version 10 Pro with HALion Sonic SE

I created a simple drum beat using some midi tracks and a drum set program selected in HALion Sonic SE.

When my friend opens the project, the tracks are loaded sucessfully, and also the HALion Instrumenst in the Instrument rack,
but the drum set program I selected was not sent to my friend and all midi notes were played with the default program in HALion : “First contact”

I guess it’s a bug ?
