In React-native i'm using 'sharingan-rn-modal-dropdown'; Dropdown in form for add and edit data but selected values not getting reflected in dropdown - react-native

Question

what exactly is happening is when i select the delivery service onChangeService i'm setting the next dropdown i.e. carrier's list.Also i'm setting the selected carrier as per the service.But all the time value is getting set correctly in {this.state.selectedCarrierName} but still i can show its label only.lists contain label an value pair
async onChangeService(value) {
//{ ...this.props.deliveryOptionsValue, selected: value.value === value }
this.setState({ newCarrierList: [], selectedCarrierName: '', selectedCararierName: '' });
const priceDeliveryService = this.props.orderDetailsDTO.priceDeliveryServiceDTOs;
console.log("carriers", JSON.stringify(this.props.carriers));
var newList = [];
var carrier = '';
await priceDeliveryService.forEach(m => {
console.log("compare", m.serviceId === value.id);
if (m.serviceId === value.id) {
console.log("carrier", JSON.stringify(this.props.carriers));
let l = this.props.orderDetailsDTO.carriers.filter(n => n.id === m.carrierId);
console.log("l", l);
if (l !== undefined) {
// / orderList: [...this.state.orderList, ...content]
// this.setState({ newCarrierList: [...this.state.newCarrierList, ...l[0]] });
newList.push(l[0]);
console.log("defa", newList);
if (m.defaultCarrierService) {
this.setState({ selectedCarrier: l[0], selectedCarrierName: l[0].name });
carrier = l[0].name;
} else {
this.setState({ selectedCarrier: newList[0], selectedCarrierName: newList[0].name });
carrier = newList[0].name;
}
}
}
});
const list = newList.map(item => ({
label: item.name,
value: item
}));
this.setState({ newCarrierListValue: list, newCarrierList: newList })
console.log("newCarrierListValue", list);
console.log("newCarrierList", newList);
// console.log("carrier service", p.carrierName, value.id);
const carrierServices = this.props.orderDetailsDTO.carrierServiceDTO;
console.log(carrierServices.length);
const pi = await this.setCarrierService(carrierServices, value, carrier);
// let pi;
// for (let i = 0; i < carrierServices.length; i++) {
// console.log("if", carrierServices[i].cdlServiceId == value.id, carrierServices[i].carrierName === carrier)
// if (carrierServices[i].cdlServiceId == value.id && carrierServices[i].carrierName === carrier) {
// console.log("mathced data", carrierServices[i]);
// pi = carrierServices[i];
// console.log(pi);
// break;
// }
// }
this.setState({ carrierService: pi.serviceName, carrierServices: carrierServices });
console.log(pi.serviceName);
