Vue drop-down refresh problem

uses the drop-down refresh of the better-scroll plug-in, but there is a problem, that is, when I drop down, I can"t pull it down in a certain position, so it gets stuck and doesn"t go back to the top.

in html

<scroll
        class="scroll"
        :pullup="true" 
        :data="data"
        @scrollToEnd="loadMore"> 

in methods

loadMore() {    //
      if (!this.hasMoreFlag) {
        return
      }
      if (timer) {
        return;
      }
      timer = setTimeout(() => {
        this._getData();
      }, 5);
    },

how to solve this problem?
