Lately the programms have been auto-translating some video titles. Not all videos, but some and those every single time.

I'm located in germany. My YouTube language is set to UK english. My location on YouTube is defined as the United Kingdom.
I watch YouTube with an english UI and a lot of videos from various places in the world.
Lately I have noticed that when downloading videos with the 4k Video Downloader, the programm will autotranslate and name the videos into german. Not all of them, the majority are still named as they are supposed to be. But some. And those all the time.
I can download 5 videos from the same account, set in the US for example. And of those, two will get their name randomly translated. No matter what I do or how many times I re-download it, it tranlslates the title.
Naturally this results in a while list of problems.
I've tried various ways that I could think of to stop this but so far to no avail. :(
