Import tracks from Project shows different tracks's volume

Hi,

I notice an issue today while importing some Folder tracks (included some audio tracks), and also Group, FX Folder.
The volume of them are different from the original project. They are lower and different, it maybe relate to the type of track, I am still figuring out.
The original Project was 1st created using Cubase, but it was saved as Nuendo Project several times.

I am working and will take some screenshots asap.

Is it possible that there were VCAs in the original project offsetting the volumes of those tracks? If that were to be the case, the tracks would be imported with their original fader value, without the VCA added/subtracted values.

Hi, I am back to attach some screenshots of the Mixer.
For additional Info, I don’t use any VCA since the automation bug was found.
The volume of tracks are different, some gain down, some gain up. Send volume is also changed.

The new Project (I created an Empty Project to test):
