Bug/Issue Issue With Tgv Duplex - Formation Designer

Hi there

I am in the middle of a stream on twitch right now trying to get the TGV Duplex to do a simple 4 Car + 2 power car Set but when i choose ANY of the TGV Power cars, none of the actual Passenger cars are showing.. the Acella works fine but for some stage and stupid reason the TGV WILL NOT behave. has any one got any tips

 

Can anyone give me an answer??
