Hi des1mgeert,
Thanks for posting. Our Dutch translation files are getting out of date, which is why you are seeing those strings in English. I’d love to have you update our translation files so they are complete again! If you’re interested, you can head over to our Getting Started thread. You’ll find all the files and instructions you need there.
All of our translations are maintained by community members, so if you are not able to update you’ll need to wait for someone else who can work on the translation.
Best,
Leah
