Login screen language selector

is there a way to change selected language in login screen language selector?
We have translated project to Estonian and set Estonian for every user in Gateway.
At the moment login screen language selector shows English by default which is misleading for users.

The Locale Selector at log in should be defaulting to whatever Java thinks your default locale is. This is usually picked up from the OS settings the first time you ever installed Java on that machine. I know this works correctly for French and Spanish in Linux and Windows, but I haven’t tested Estonian.

If you don’t need the Locale Selector for any of your users, you can simply not show it. In the Designer, choose Properties in the Project menu. In the dialog that comes up, go to Client > Login > Show Locale Selector and change the setting to “hide”.
