Vissim/Lumen error with vehicles in Lumen?

When attaching a Vissim model to Lumen, the vehicles run as expected, with one major error. The vehicles are overlapping, meaning that a combination of 20+ vehicles will be all pushed together. See picture below. 

Initially this does not happen in the Lumen model, however once the movie editor is launched, the movie editor and the model both show this error. The Vissim model is running as expected, it seems to be some error with the time settings in movie editor?
