I have an annoying issue, quite similar to [this one]
The difference here is that I have a language entry for chinese when I want to swich between keyboard layout (french, english, and this bloody chinese). I want to remove the chinese entry, since I uninstalled the software for this (Sogou). But in the available languages from the windows language panel, I only have french and english. I tried to add a chinese layout and remove it, without success.
Here some pictures describing my issue : https://i.stack.imgur.com/B9vxJ.jpg

Any lead would be appreciated, thanks in advance !

- Be careful about the input name (not only the language name)
- Reboot between adding the inputs and language and removing it
