I tried to reproduce this, but I haven't been able to find any service with two MPEG streams in German and English. Maybe you can point me to the exact channel?
Anyway: in the situation as displayed in your screenshot English should have been chosen. I can think of two valid reasons when this is not the case:
1- You previously (manually) selected an other language and E2 remembers that, or
2- The languages are not advertising themselves correctly as German & English (in the stream; nothing you can do about that).
If the latter would be the case, it sometimes helps if you select 'original' (that might be the second audio selection in your setup).
