I have a FileBasedProject with :

• Language pair: "de-DE" to "en-GB".
• One file "fruits.xml".
• One DeepL MT Translation Provider.

Attempting to run the following code via the API completes without errors but does not pre-translate the file (no translations in the target segment):

    FileBasedProject ThisSdlProject = new FileBasedProject(SdlProjectFilePath);
    
    var settings = ThisSdlProject.GetSettings();
    var preTranslateSettings = settings.GetSettingsGroup();
    preTranslateSettings.NoTranslationMemoryMatchFoundAction.Value = NoTranslationMemoryMatchFoundAction.ApplyAutomatedTranslation;
    preTranslateSettings.TranslationOverwriteMode.Value = TranslationUpdateMode.KeepExistingTranslation;
    preTranslateSettings.MinimumMatchScore.Value = 75;
    ThisSdlProject.UpdateSettings(settings);
    
    ProjectFile[] translatableFiles = ThisSdlProject.GetTargetLanguageFiles(new Core.Globalization.Language(CultureInfo.GetCultureInfo(TargetLocale)));
    
    AutomaticTask preTranslateTask = ThisSdlProject.RunAutomaticTask(
        translatableFiles.GetIds(),
	    AutomaticTaskTemplateIds.PreTranslateFiles
    );
    
    ThisSdlProject.Save();

However, if I select the file in Studio 2021, Batch Tasks -> Pre-translate -> Finish (without changing any settings), it works:

I swapped the DeepL MT Translation Provider for a File Based Translation Provider (Test_de-DE_en-GB.sdltm) and tried it again, and it worked as expected:

Are there additional settings that must be applied in order for MT Translation Provider pre-translation to be applied via the API?

Thanks in advance,
