Audiochannel-Grouping for Loudness Effect in the Export Workspace is not available

The audiochannel-grouping options for the loudness effect in the new export workspace is not available in the German version of Premiere Pro. You can only see the headline but all options are not visible in the export dialog anymore. 

The only workaround to configure audiochannel groups is to create an export preset in Media Encoder and import this into Premiere Pro.
