All POIs in Bushtalk Radio are broken in WU6 (all 3rd party POIs?)

All the POIs in Bushtalk Radio are now at ground level and go below ground and disappear entirely when you are about 2 miles from them.

The normal flight sim POIs look fine.

Did something change in the POI code? Is this something I can fix locally, or do I need to wait for the Bushtalk dev to fix them?
