来自数据库的标签值未显示在React Native标签列表上

Question

here is the problems 红色突出显示：问题（我认为） 蓝色突出显示：工作正常

这是我目前面临的问题 Current situation 标签列表未显示从数据库表中获取结果标签的值

真实标签列表视图必须像这样 enter image description here 例如：a是从数据库获取结果中的值

在添加此$ fetch_label = array（）; *后突出显示黄色 就像在我给的图像中一样，未分类的标签值正在显示，但是我之前添加的其他标签并没有显示它只是显示空白标签，请帮助我。 我的完整代码预览
