Can't see flow trajectories

Hi there I have an unusual problem with a study...

Basically I did the simulation where I was checking the temperature inside a cabinet, I did two versions to verify different cooling fans. So after the results were ready on version will load and display the flow trajectories, the other version basically it created the trajectories but they won't display...

I already checked if I made a mistake not selecting the right thing to plot but they are both set for temperature(fluid). 

Anyone knows why I can't see the flow trajectories in one of the version?
