Saved language is not shown in admin settings
Description
The setting regarding the languages of the instance (in https://example.com/settings/admin/settings) is blank every time I open the page. I can set the languages and hit save, and the new languages are shown in the about section correctly; but when I open the setting page again, the field is blank, so if I hit save the languages of the instance get reset and erased.
Expected behaviour:
The current languages of the instance should appear in the field of the settings page.
Actual behaviour:
I think the field is not checking for the current value of the languages of the instance.
Reproduces how often:
Always.
