If you are having issues with the launcher being in a different language than normal there are a few places you can check to reset it.
Within the Launcher itself, the user can change the language by selecting the world icon found next to the session timer that ticks down in the launcher environment. To change the language back simply click the globe icon and select the desired language for the launcher.
In Station Monitor
The language can also be changed within the Station Monitor by accessing the additional options for the station.
To change the language from your Station Monitor click the "..." symbol on the station card that needs the language changed.
Select the correct language from the dropdown menu and click "Save" at the bottom of the screen. The launcher should now change to the selected language.
