Hi Ty and welcome to our forum,
Open the Form Template in the Designer, go to site, click Modify Settngs and Columns, and Edit Template. Once the form is open, go to Tools->Form Options->Form Library Columns. Add your newly added items. Re-save the form (ctrl-s) or File-Save. Close the form. You should be in business!
