Hello everyone

As the title states, Word overrides some special characters I type in, sometimes with functions, sometimes not.
I have a German keyboard so my layout is different, and I also checked that Word is using German keyboard layout when typing.

Example
I type: "[" which requires me to use CTRL + ALT + 8.
I get: A decrease in the font size.

I type: "{" which require me to use CTRL + ALT + 7
I get: Nothing. Nothing shows up or visually changes in the document or settings.

These are just two examples of several that happen.
I have reinstalled Word already, but the problem persists.
I also verified that this is an isolated Word problem as other programs I tested this with, even the ones that are natively in English, correctly display the characters typed.

I also have checked the keyboard shortcuts option in Word to see if, for some reason, Word has created different shortcuts than usual. This is not the case. In fact, Word displays that shrinkfont actually has a different keyboard shortcut, so even if I wanted to go through everything manually and change the shortcuts, I can't.

Windows 10
Word 2016

Any ideas?
Thanks
