when you enter the value of key in the input box to search, it is clear that the data is found, but it is not displayed, it is automatically displayed on the check box, I do not know what the reason is, solve

<Transfer
    dataSource={mockData}//mockData
    listStyle={{width: 300, height: 300}}
    showSearch
    filterOption={this.filterOption}
    targetKeys={targetKeys}
    onChange={this.handleChange}
    render={item => item.title}
    footer={this.renderFooter}
/>
