Reference setting Display Overrides not working

Using OpenRoads Designer 2020 Release 2 which is built upon Microstation CONNECT update 13.

I have a container file that is referencing files A B and C. This container file is referenced into a sheet file, Live nesting depth 1. The reference setting Display Overrides is set to never so that I can control the display of all of my sheets from the container file. This setting is not working - in the example I provide in the attached Zip file - the sheet file has no levels displayed even though all levels are displayed in the container.....

I'm sure this is something incredibly simple but I'm not even sure where to look...

Update: 

It works....The issue ended up being a configuration variable. I was making changes trying to fix another issue. I went back to an old config file and the levels were displayed as expected. 

Now I just wish I knew which config variable gave me the issue....
