[Post-Vis] Wrong attributes displayed

If you click on an agent in the postvisualiation and look at its free-flow velocity it might not coincide with the attributes that you've chosen for the source. The reason is that the PostVisualation can only display information that is available in postvis.traj. For missing data, arbitrary values are shown which can be misleading for users.

What is the expected correct behavior?

It should only be display correct information (from postvis.traj) to the user. All other fields could e.g. set to N/A or similar.
