Translation for isPostsPage is set to false

[MKlblangenois]

When I'm making a query to get the posts page, translated page return false for value isPostsPage.

Reading settings is configured on the good page.

Query :

{
  pages(where: {name: "blog"}) {
    nodes {
      uri
      isPostsPage
    }
  }
}

Result

{
"data": {
    "pages": {
      "nodes": [
        {
          "uri": "/blog/",
          "isPostsPage": true
        },
        {
          "uri": "/fr/blog/",
          "isPostsPage": false
        }
      ]
    }
  }
}

this plugin does not interfere with the isPostsPage in any form (at least not intentionally).
