老师好，使用mescroll-uni实现上拉加载、下拉刷新为什么一直显示加载中

Question

<template>
  <view class="dividend-list-container">
    <empty-data v-if="isEmpty"></empty-data>
    <mescroll-body
      v-else
      ref="mescrollRef"
      @init="mescrollInit"
      @up="upCallBack"
      @down="downCallBack"
      :up="{
        textNoMore: '--我也是有底线的！--',
      }"
    >
      <block v-for="(item, index) in resultList" :key="index">
        <history-netvalue-item
          :item="item"
          surceType="dividendMethodList"
