Your problem
My problem is:

I have a multilingual mautic system (englisch/german) and would like to customize the individual texts in the pereference center. Is there a way to do this properly without touching the core files?

E.g. i would like to change the text “I want to receive email” to “Yes, please send me e-mails” which is the language string “mautic.lead.contact.me.label” but i guess the file is overwritten with every update?

Thanks in advance!
