Bluetooth keyboard issue on f key
I am using a Bluestork bluetooth keyboard on my macbookAir M3, so far without problems. Now my f-key gives me a "ƒ" (the symbol for math function instead of the letter "f". Capital f gives "·" instead of "F".
I tried to fix via system preference : keyboard and language settings but I cannot find how to fix this. Also searching on the internet doesn't help me further.
Anybody has an idea how to fix? Thanks!
MacBook Air 13″, macOS 14.5
