Fields With a Fixed Set of Values
Most contact fields take whatever you type. Two do not, and the action gives you a picker for each rather than a text box: Time Zone and Primary Language.
Both hold a standardized code — an IANA time zone identifier like America/Denver, and a
language tag like ES or FR-CA. A value outside those sets is not stored, so the picker is
how you know the value you chose will actually land. You can search either list by typing.
The picker starts empty rather than on your own time zone. The value you set here describes the contacts the action writes to, not you.
If you copy the value from another field instead of choosing one, a language name is accepted
and normalized on the way in — a CRM field holding French is stored as FR. The same is true
for time zone casing: america/new_york is stored as America/New_York.
An empty value is neither a valid time zone nor a valid language, so leaving the picker empty sets nothing — it leaves whatever the contact already had. That is deliberate: a blank time zone breaks date rendering in emails, and a blank language is not the same fact as "we don't know theirs". To remove a value, clear it on the contact's Contact Details page.
