Hallo Frank, grĂ¼ss dich,
Thanks for reaching out with your question.
Unfortunately at the moment it is not possible to translate those 2 fields. I will create an internal ticket for that so our developers can look into it what can be done.
Meanwhile I can suggest the following workaround.
1. Put all language content in the box, and have the different languages surrounded by a <span class=”en”> or whatever the language is. Like this:

2. Display only the language appropriate span with css, something like this:
.tribe-events-before-html span { display: none; } /* Hide all spans! */
html:lang(en-us) .tribe-events-before-html span.en { display: inline; } /* Show English */
html:lang(de-DE) .tribe-events-before-html span.de { display: inline; } /* Show German */
The same can be done for the text below.
I hope this helps. Let me know.
Cheers,
Andras
