Your problem is related with the layer states. For unknown reasons both layer states defined in your DXF contains three entries for the layer "0" properties which doesn't make much sense, there should be only one entry per layer. Anyways in the next update duplicate entries will be automatically removed. For the time being you can manually delete the duplicates from you original drawing.
