[Resolved] Split: Page lists block is empty in translated page content

Problem:
The client reported issues with the page list block not working correctly on translated pages. Specifically, the page list in content disappears, and in navigation, it incorrectly displays a submenu from a previous translation instead of the current one.
Solution:
We recommended adding custom XML configuration to resolve the issue. Here are the steps:
1. Navigate to WPML > Settings > Custom XML Configuration.
2. Add the following code:

<wpml-config>
  <gutenberg-blocks>
    <gutenberg-block type="core/page-list" translate="0">
      <key name="parentPageID" type="post-ids" sub-type="page">
      </key>
    </gutenberg-block>
  </gutenberg-blocks>
</wpml-config>

3. Save the changes.
4. Go to your default language page, make a small change, save, and re-translate. This should correct the display of pages in the page list block on translated pages.
