Hi,
I changed some values of the given "Title" field under the config/display/extra fields
there was the selection for Mr, Mrs, Ms, Dr and so on. I wanted to change some values - see picture 1.
In the frontend the selection displays the variable value instead of the title. see pic 2.
How can this be solved?
Where do I need to take care in any form for an Mail or so on, so that the template uses the correct things I need to use?
Where do I have to change something into an Mail-Template or other forms, when I integrate some more custon fields (like company name, when "company" is selected... )

kind regards
