Polygon Collections on unassigned levels

We have a BM project using a an Oracle data source. We would like to use a dgnlib for all the levels. That way we only need to define PBA for the levels names and let color, weight and style go ByLevel. Save me a lot of configuration and also overhead when reading the data.

It seems to work fine except for Polygon Collections. These elements ends up on the correct level and get the correct attributes. BUT in Level Display the level is unused (see image below). This means that the level cannot be turn on or off. If I skip the dgnlib everything works fine (except that we have to define all the attributes in GSA also).

Works the same in SS2 and SS3. Not tested in SS4.
