Where are the civil materials located that come with Open Rail?

Using OpenRail Designer CE 2021 Release 1

If I create a brand new file using the default open rail seeds. I would expect to see the "Civils" or "Bentley-Civils" palette available when trying to apply materials.

I have searched the c:drive locations specified in the config and cannot find any new materials or dgnlibs that come with the software.

Specifically I am looking for the aggregate materials that come with the bentley civils packages.  Not the standard "Stone&Gravel" in mircrostation

Has something changed?  Or am I barking up the wrong tree?

Thanks
