After importing template form from another site and importing into new site, all of the column variables do not show up to add in required form fields. The columns exist on the new site but to not appear as an option to insert them into the needed fields. The fields have rules that require the column variables. When I try to save, there rule containing the required field states it's an invalid rule because the "variable is no longer available".  It should be available because the column the variable represents exists.
