Update react detail page after using patch - React

Hello I’m building simple app that has a list of shipments pulled from json server fake db and after clicking item on the list detail page appears and i have method to update one field (shipment name) i used patch method and it works but after closing modal my name don’t update immediatelly on the detail page i tried componentdidupdate but im doing something wrong.

export default class ShipmentsDetails extends Component {
  constructor(props) {
    super(props);
    this.state = {
      shipment: [],
      openModal: false,
      error: null,
      isLoading: false,
      name: ''
    }
  }
  componentDidMount() {
    this.setState({
      isLoading: true
    })
    const id = this.props.match.params.id;
    fetch(`http://localhost:3001/shipments/${id}`)
        .then(res => res.json())
        .then(data => {
          this.setState((state) => ({
            shipment: data,
            isLoading: false
          }))
        })
        .catch(err => {
          this.setState({
            error: err
          })
        })
  }
  componentDidUpdate(prevProps, prevState) {
    if (this.state.shipment !== prevState.shipment) {
      this.setState({ shipment: this.state.shipment });
    }
  }
  showModal = () => {
    this.setState({
      openModal: true
    })
  }
  hideModal = ()=> {
    this.setState({
      openModal: false
    })
  }
  handleChange = event => {
    this.setState({
      name: event.target.value
    })
  }
  handleSave = () => {
    const name = this.state.name;
    const id = this.props.match.params.id
    axios.patch(`http://localhost:3001/shipments/${id}`, {name})
    .then(res => console.log(res.data));
    this.setState({
      name: '',
      openModal: false
    })
    this.hideModal()
  }
