When I created a Communication Templates New and I selected Add Translation > Locale (any language), the System created a New Communication Template, but does not really do the translation to the corresponding language.
CSM will not translate new communication templates. And, actually, it doesn't translate the out of the box ones either. What happens is that we have a repository with OOTB translations for the OOTB templates and when you create a new localized template it will check that location and see we already have a template for the locale you are creating. Then it will make it available in your slice.
If you make changes to the default text and create a new localization your changes will not be in the localized text and you will have to do it again.
