Geospatial Admin - Symbology Priority

Hello Community,

I hope someone of you can bring me to light according to following problem, I couldn't find any information in the internet yet.

In Bentley Geospatial Administrator it's possible to set up display priority for features. In the attached screenshot you'll find my configuration sample. Unfortunately the display priority doesn't work as imagined. I created a DesignFile with Oracle Connector but regardless of what I set up, there's no impact in display, the first element written into the file lies below the second element. I'm using Microstation V8i (SS3) with Bentley Map.

Thank you in advance,
Maik
