Why does iOS Dictation change "BMW" to "Bayerische Motoren Werke"?

I have a problem with the German iOS dictation feature.

My problem is that (when selecting the German keyboard) the word “BMW” is always automatically turned into „Bayerische Motoren Werke“, which makes no sense. This isn’t an issue when selecting the English keyboard, but it is an issue with a German keyboard.

I’ve reset the keyboard dictionary and turned off AutoCorrect nothing helped!

Do you guys have a solution for this?
