{preferredchannel} language and text

My Mautic version is: 4.4.10
My PHP version is: 7.4
My Database type and version is: MariaDB 10.5

My problem is:

Is there a way to change the text and font family accompanying preferredchannel and frequency? Currently it’s a mix of English and German

Steps I have tried to fix the problem: Changed the landing pages language setting from de-de to de. Changed the font family in the builder.

Now after switching to Mautic 5 it’s just English. Is there really no way to change the language and/or text? My system settings are set to German.
