Hey Alexander,
Thanks for reaching out! We unfortunately only provide support in English here—we do try to provide multilingual support when available, because our team is multilingual, but we mostly provide it in English.
Using Google Translate, I was able to translate your message as this:
I just did the update 4.3 of the modules the event ticket.
The display problem of the field set ticket fields is always present: it does not appear in the email.
With the plugin that you sent me it worked …
the bug is still present?
Below is a screenshot of the email.
This is currently a known bug that we are working hard on fixing — it is listed on our Known Issues page and I will post an update as soon as there is news on the fix.
Sorry for the trouble! 😀
