Woocommerce products can not be queried in another language

[cankahya]

The following query should return the english versions of the products. Instead it returns the main locale (german in this case):
Query
{ products(where: {wpmlLanguage: "en"}) { nodes { id slug name ... on SimpleProduct { id name buecherFields { buchKategorien { nodes { name slug } } } buchInfos { buchInfos } locale { locale id } } } } }

Response

  "data": {
    "products": {
      "nodes": [
        {
          "id": "cHJvZHVjdDoxMDE4Mg==",
          "slug": "sollberger-boegli",
          "name": "Sollberger Bögli",
          "buecherFields": {
            "buchKategorien": {
              "nodes": [
                {
                  "name": "De aedibus",
                  "slug": "de-aedibus"
                }
              ]
            }
          },
          "buchInfos": {
            "buchInfos": "<p>Herausgegeben von: Heinz Wirz<br />\nTextbeitrag: Katharina Marchal</p>\n"
          },
          "locale": {
            "locale": "de_DE",
            "id": "de_DE"
          }
        },
....

Not sure if this is a bug with wp-graphql-wpml or with the woocommerce plugin. Clarifcation would be great!

This is a very crucial feature, which makes the use of graphql for multilangual woocommerce sites impossible.
Please priotize.

Also happy Thanks for any tip!
