The problem here is that the objects you are importing have multiple materials applied to them. Cinema 4D is then treating each material as it's own object and then giving an offset to the second material.
To fix this in Cinema 4D go to the object list and select the object that is being offset. Then remove the protection tag for that object. Then reselect that object (it will be deselected) and set the coordinates to 0,0,0.
