Cinema 4D doubles vertizies

Hey guys,
i go crazy on this, when i import a 3d model from c4d the vertizies are doubled.
Inside of c4d i got 111 points, after importing the empty model (no texture, no uvms, no material) the count jumps to 266.
Anyone got a idea why this is happening? Do the normals need to get smoothed?

Thanks a lot!

Run the test and see for yourself.
When you smooth the model - the vert count will read as desired.
226 is odd - un-smoothed should be 222.
