范围功能在模板中提供了额外的输出

I am following this link to figure out how to create an archives page. I am using the hugo-xmin theme with slight modifications.

As far as I understand, range goes through the pages and should print them out. But, I am getting an additional 0001 also. I don't understand why. I'm still a beginner to Hugo and Go.

My output (circled portion in red not what I want)

My archives.html

{{ partial "header.html" . }}

<div class="article-meta">
<h1><span class="title">{{ .Title | markdownify }}</span></h1>
{{ with .Params.author }}<h2 class="author">{{ . }}</h2>{{ end }}
{{ if (gt .Params.date 0) }}<h2 class="date">{{ .Date.Format "2006/01/02" }}</h2>{{ end     }}
</div>



<main class="content" role="main">
    <div class="inner">
{{ range (.Site.RegularPages.GroupByDate "2006") }}
<h3>{{ .Key }}</h3>
<ul>
  {{ range (where .Pages "Type" "post") }}
  <li>
    <span class="date">{{ .Date.Format "2006/01/02" }}</span>
    <a href="{{ .RelPermalink }}">{{ .Title }}</a>
  </li>
  {{ end }}
</ul>
{{ end }}
</div>
</main>


{{ partial "footer.html" . }}

My archives.md

title: "Archives"
layout: "archives"

I changed my archives.html to the following, with some help from hugo-lithium. It works for my use case now. But I still don't understand why the 0001 came up in the first place. So I will not be marking my answer as correct for now.

{{ partial "header.html" . }}

<div class="article-meta">
<h1><span class="title">{{ .Title | markdownify }}</span></h1>
{{ with .Params.author }}<h2 class="author">{{ . }}</h2>{{ end }}
{{ if (gt .Params.date 0) }}<h2 class="date">{{ .Date.Format "2006/01/02" }}</h2>{{ end     }}
</div>


{{ range (where .Site.RegularPages "Section" "!=" "").GroupByDate "2006" }}
  <h2>{{ .Key }}</h2>
  <ul>
  {{ range .Pages }}
  <li>
    <span class="date">{{ .Date.Format "2006/02/02" }}</span>
    <a href="{{ .RelPermalink }}">{{ .Title }}</a>
  </li>
  {{ end }}
  </ul>
{{ end }}



{{ partial "footer.html" . }}
