Hi there, I noticed that some system error messages in JSM are still displayed in English, even though both the customer portal language and the JSM project language are set to German.

In detail, we have:
- Configured the language support to German
- Set project default language to German
- Customer profile settings are set to German language too
Is there a way to have these system error messages localized to German
and if yes, where this can be configured?
Side-note on about how we reproduce this error:
The approver later clicks "Decline" again from the approval email, the resulting error page comes up
