Editable grid dropdowns

Hello, I have editable grid in which I have 3 dropdowns, I'm picking up the values and choices from constants and have rule decisions based on that now for the first row it's working perfectly fine I select "Region" then "Country" and then "Language", but once I add new row I loose all the values from second and 3rd dropdowns and they become blank and I'm not able to select anything.

Here is the full code for the a!foreach is it something within the add row function?

                    rows: a!forEach(
                        items: ri!AOS_Documents_Required,
                        expression: a!gridRowLayout(
                          id: fv!index,
                          contents: {
                            a!dropdownField(
                              choiceLabels: cons!AOS_Regions,
                              choiceValues: cons!AOS_Regions,
                              label: "Dropdown",
                              labelPosition: "ABOVE",
                              placeholder: "--- Select a Value ---",
                              value: fv!item['recordType!AOS_Documents_Required.fields.Region'],
                              saveInto: fv!item['recordType!AOS_Documents_Required.fields.Region'],
                              searchDisplay: "AUTO",
                              validations: {}
                            ),
                            a!dropdownField(
