Hi @dennisth19,
I hope you are well today and thank you for your questions.

Therefore, some terms are in English.:
Could you please tell me how you have set German as main language?
Also, please tell me what is your question here?
2. Is there a way to use the backend in English and the frontend in German?
Yes, if you have not translated the backend of your site then it displays in English.
