Hi @TimothyR4,
Thank you for reaching out to us through the Community. In order for you to change the custom field name, you will have to go to "My Settings" that is located at the top right corner tab located to the right side of the "Help" tab. Once you get to your settings, scroll down until you see a "Contact Settings" section and click on "Manage my custom fields." You should be able to then edit your custom fields and change their names. For more information on this, please click here for our Knowledge Base article. Let us know if you need assistance with anything else.
