Steps to reproduce

1. Add the automated translation bundle: https://github.com/ibexa/automated-translation
2. Configure it: 
   1. in bundles.php move 

Ibexa\Bundle\AutomatedTranslation\IbexaAutomatedTranslationBundle::class => ['all' => true],

before 

Ibexa\Bundle\AdminUi\IbexaAdminUiBundle::class => ['all' => true], 

2. Add config:

ibexa_automated_translation:
    system:
        default:
            configurations:
                google:
                    apiKey: "google-api-key"
                deepl:
                    authKey: "deepl-pro-key" 

1. Add jQuery - yarn add jQuery and autoProvidejQuery() to webpack encore
2. Try to translate any content

Result

The source language is grayed out with information that there are no options to choose from

Expected

possibility of translating content from any source language to the target language through the selected translation system (manual/deepl/google translate)

The second problem is that if I manage to select languages, an error appears
