Levels in a Reference all go to "Default" instead of individual levels

Hello everyone, here is my situation:

In what I will call Basemap "A", I used Bentley Map to import features from a GIS database into my DGN. Before importing the features into Basemap A as elements for manipulation, I changed the symbology of the levels to standard level names for sidewalks, driveways, etc. (i.e. "PV_X_Walk", "PV_X_Driveway")  Once that was complete, I saved settings then opened what I will call Basemap "B" and referenced in Basemap "A". All of the symbology, level name, etc. that I specified in Basemap "A" seems to have been lost in translation, and all of the level names I would expect to see in my level manager have been turned back to Default. When I hover over an element, I can still see the Native element layer name, but the Microstation level and symbology is Default. I would suspect this to be some setting I can alter in my reference attachment window, but I can't seem to find a solution right away.

Any help with this would be appreciated! Thanks.
