Welcome to the community, @Leslie_Cooper1!
When you change the name of a field, it changes everywhere across your entire base. To change the name of the field, you will need to click on the name of the field and then choose “Customize Field Type…”.
However, on the form view, you are also given an additional option of creating a “special name” for the field that will ONLY appear on your form. This will not affect the name of your field… it only affects the name that is displayed on the form. This way, you can show your form users a “form-only name” for the field when they’re filling out the form, without affecting your “internal name” of the field. This was really a stroke of genius by Airtable, because your public-facing field name won’t interfere with the name of your field internally.
