USelectMenu设置默认值时显示ID而非标签的问题求助

我现在在尝试给USelectMenu组件填充选项并设置默认值，但遇到了一个头疼的问题——控件显示的是ID字符串而不是对应的标签名称。我已经把原始数据转换成了{ label, value }的格式，默认值也指向了目标公司的ID，但就是不显示标签。以下是我的完整代码，麻烦帮忙看看哪里出问题了：

<template>
  <div class="p-8">
    <h1 class="text-2xl font-bold mb-4"> Test Page </h1>
    <p class="mb-2"> This is a minimal Vue page. </p>
    <div>
      <div>{{ companyOptionsTest }}</div>
      <USelectMenu v-model="selectedCompanyTest" :items="companyOptionsTest" placeholder="Select a company" />
    </div>
  </div>
</template>

<script setup lang="ts">

const companyOptionsTest = testCompanies.map(company => ({ label: company.name, value: company.id }));

// Set default to Bihar's id
const selectedCompanyTest = ref(
  testCompanies.find(c => c.name === 'Bihar')?.id || null
);
</script>

<style scoped>
/* You can add page-specific styles here */
</style>

我检查过companyOptionsTest的数据格式是对的，默认值也确实是存在的ID，但USelectMenu就是直接显示ID文本。有没有大佬能指点一下问题所在？
