the bug (see https://symfony.com/releases for the list of maintained branches).

See:
https://symfony.com/doc/7.4/reference/forms/types/currency.html#legal-tender
> This option determines if the choice values should be translated and in which translation domain.

this notice is shown twice, once for [choice_translation_domain](https://symfony.com/doc/7.4/reference/forms/types/currency.html#choice-translation-domain) (good) and once for [legal_tender](https://symfony.com/doc/7.4/reference/forms/types/currency.html#legal-tender) (bad)
