From one of the HiWis:
if you select a track and switch the object type (i.e. from head bbox to bbox) sometimes the head bbox is saved as bbox instead of the annotated bbox
Another:
but actually there's this small bug when you switch from bbox to person mid-annotating, the annotation table does not smoothly change to person obj type. and you have to close and re-open the table.
