Holes in shapes do not work when importing from shapefiles

Hi all

When we import a shape file into Bentley Map SS1 holes are getting "filled".

A simple test:

See the attached dgn file.

1) On level "Original - with hole" I have made a simple shape with a hole.

2) I then export it to a shape file. And checked that it is exportet correctly (it is)...

3) Then I import the shapefile again - the result can be seen on level "Importet - no hole" - and now the hole is gone...

Is this a bug or a feature? Or am I missing something?

Kind regards

Morten
