Hi theedge,
Thanks for getting in touch. It looks like the German translation for The Events Calendar (and Events Calendar PRO) is outdated, which is why you are seeing more words in English. Would you be willing to work on updating the translation? Then all the words will show correctly. We’d be happy to give you a free license in exchange for your work.
If you’re willing, check out the Getting Started post where you’ll find the instructions and files you need. If you are not able to work on the translation, you’ll need to wait until another German speaker volunteers to work on it and we can update the files.
Best,
Leah
