     setIsWorking(true);
     const updatedData = helpers.normalizeData({ ...wizardData, ...stepData });
+
+    copyFields(updatedData, fieldsToCopy); 
+
     setWizardData(updatedData);

     // Check if the selected state is a no fly state

copyFields is:

function copyFields(updatedData, mappings) {
  for (const { from, to } of mappings) {
    if (updatedData[from] && !updatedData[to]) {
      updatedData[to] = updatedData[from];
    }
  }
}

In the config send that new prop:

fieldsToCopy: [
  { from: "country", to: "personMailingCountryCode" },
  { from: "state", to: "personMailingState" }
]
