Changing tempo changes volume sliders of tracks grouped in VCA

I have five tracks grouped together in a VCA. I automate the volume of the VCA earlier in the track, and when the playhead is after that point in the track, when I change the tempo, the volume sliders for the tracks within the VCA (not the VCA itself) are reduced to completely silent.

I’ve attached a gif of the issue at hand.

Hi and welcome,

Could you try in Cubase Safe Start Mode, please?

Could you make a new GIF with the whole screen, please? I don’t understand all details here. I’m not sure if you are in playback or stop. Where is the playhead cursor currently, in which state are the automation curves regarding to playhead cursor, etc.
