Welcome to the community, @Greg_Woodbury! :grinning_face_with_big_eyes: Check the view toolbar (above the grid). Chances are that the new fields are hidden. Look for something like this that indicates hidden fields:
Click on that to open a list of all fields and see which ones are hidden.
Would you be able to share screenshots of your grid view and the new form view? One thing to keep in mind is that if you change how a field is labeled in the form view, that only changes the form view label. The field’s original name remains unchanged. Clicking on a field header in the form view will show you both the current label as well as the actual field name.
