Hey Planetcrypton,
Thanks for getting in touch. For this, when you are referring to the form labels are you referring to the actual field names? If so, those will always display specifically as entered within the list itself in MailChimp. For making the display names of the fields different from what is stored within MailChimp, you could instead try using the Embedded Form code from within MailChimp and modify the display labels for each of the fields within the copied form code. (This guide shows how to get the form code: https://eepurl.com/gOGN)
However, if you’re talking about something else, please let us know! We’ll be happy to answer as best we can!
