I have a question about adding a translation memory to a project. Is there a way I can set the Penalties of a translation memory programmatically?

I have tried something like the code below but it doesn't seem to work.

(I working with filebased projects)

Language trgLanguage = new Language(CultureInfo.GetCultureInfo(trgLocale)); 
ISettingsBundle settings = project.GetSettings(trgLanguage);
TranslationMemorySettings TMSettings = settings.GetSettingsGroup<TranslationMemorySettings>();

            TMSettings.MissingFormattingPenalty.Value = 10;

            TMSettings.DifferentFormattingPenalty.Value = 20;

            TMSettings.MultipleTranslationsPenalty.Value = 30;

            TMSettings.AutoLocalizationPenalty.Value = 40;

            TMSettings.TextReplacementPenalty.Value = 50;

            project.UpdateSettings(trgLanguage, settings);
