This is how my language settings are currently configured:
As you can see, the default language should be English and I set the keyboard layout in Options to be Swiss-French. That's the only keyboard listed in there.
But randomly, the keyboard will switch to US-EN. Also, some apps are mixing both French and English in the UI, like this:
I removed the language switching shortcuts so I know it is not that causing the issue. What else can I do to lock the keyboard to CH-FR and have it never change back to US-EN? This is driving me nuts. Also, what can I do about the weird UI?
