Export and import the same selected tracks PROBLEM

When I export the track it exports as vst and fx track, which is on the send of the track. When I import the track back in the cubase they are not connected the same way as they were when I exported them.
Fx is still there and it is visible on the track but they are not connected to each other. When you play the vst there is no effect on it.
Tried on 2 PCs with Win 11, same result. On the second I installed Cubase 12 for the first time. Clean installation, activation, went ok but the problem is the same.
