Expected Behavior

I expect the page.title and pages.lang variables to render correctly on bundle exec jekyll build

Current Behavior

Consider this frontmatter for a page:

---
layout: single
title: Über uns
permalink: /about/
page-id: about
header:
  overlay_image: /assets/images/NetInnovate_TitleImage.png
lang: de
toc: false
---

The following code snippet:

  <select id="language-switcher-select" autocompletion="off" onchange="window.location.href = this.value;">
    {% for lang in site.languages %}
      <option value="{{ lang }}" {% if lang==page.lang %}selected{% endif %}>{{ site.data[lang].l10n.lang_name }}</option>
      <!--  {{ lang }} , {{ page.lang }}, {{ site.default_lang }}, {{ page.title }} -->
    {% endfor %}
  </select>

Renders as:

  <select id="language-switcher-select" autocompletion="off" onchange="window.location.href = this.value;">
    
      <option value="en" selected>English</option>
      <!--  en , en, en, Revolutionizing ITSM with AI: Automating Issue Classification and Resolution -->
    
      <option value="de" >Deutsch</option>
      <!--  de , en, en, Revolutionizing ITSM with AI: Automating Issue Classification and Resolution -->
    
  </select>

Here the page.lang and page.title variables are wrong. Their values are actually taken from the frontmatter of the first file in the ./_posts folder. The frontmatter of that file is:

---
layout: posts
title: "Revolutionizing ITSM with AI: Automating Issue Classification and Resolution"
date: 2023-11-15
categories: AI
lang: en
---

Code Sample

Steps to reproduce

I use github CodeSpace to run my code.

Repo: https://github.com/yonz2/netinnovate

So to reproduce, create a codespace for the repo, run bundle update followed by bundle exec jekyll build and inspect the generated output in e.g. ./_site/de/about/index.html

Just curious, was this working properly before 4.3.3 released a few weeks ago? I'm experiencing some other bugs -- possibly related, possibly not -- where code that was working fine previously now throws Liquid errors, and I'm wondering if the last release broke some things.

Not sure ... I gave up on this and re implemented everything in Hugo
