Thanks for your patience here Oliver. I was able to check that out and identify the problem. Since that string is used with Additional Fields, it needed to have the PRO text domain. It currently has the-events-calendar. I’ve noted that to be fixed for our next release. Thanks again for catching it!
@Leah: thanks for the info! Sounds good! 🙂
@Josh: unfortunately I couldn’t finden the reason for the issue. But I use noch a simple workaround: I use a Company “,” instead of ” um “, which works very well. For now I don’t need any further help.
