Mail translations in campaigns ignored?

Your software
My Mautic version is: 4.4.x
My PHP version is: not relevant
My Database type and version is: not relevant

Your problem
My problem is:

We build a multi language campaign. We created mails, that have several translations.
I would think, that based on the “preferred local” of the user, the language version of the mail will be send. If there is no match, the main mail should be send.

However, in the campaign action I need to select a language version explicitely. Is this correct?
This would mean I need to check for each single mail explicitely, what the preferred language is?

This would even colide with that issue, if its still broken:
