Missing attributes in Shp export

Hi, I have a set of dgn + access database that I can't export properly to shp using Bentley Map. I think the problem is data related because I have several other projects that can be exported ok. The problem is that the shp file contains no attributes after it is exported. The geometry is ok but the .dbf is empthy exept for a Geometry_A and Geometry_P column that are not originating from my database. The elements look ok in Bentley Map can be revived, annotated, used in Map_Manager symbology and I can use the sql review command. If I use Preview in in the export dialog I see none of my  attributes there only Geometry_A and Geometry_P.

I am using Bentley Map version 08.11.07.113

I wold be gratefull if anybody avare of anything that might explain this could give me a hint.

regards
