Invalid price results for products in storefront API

[Alexander82]

We are running against the latest Storefront API in a private app to query our products. Yesterday everything worked fine, today pricing changes are no longer reflected within the API.

We have the following product listed

As you can see the min and max price are different.
When using the following query

import { gql } from 'apollo-angular';

export const PRODUCT_QUERY = gql`
    query($handle: String!) {
        productByHandle(handle: $handle) {
            id
            tags
            handle
            description
            title
            images(first: 1) {
                edges {
                    node {
                        transformedSrc(maxWidth: 350)
                    }
                }
            }
            metaFieldsGlobal: metafields(first: 10, namespace: "global") {
                edges {
                    node {
                        key
                        value
                    }
                }
            }
            metaFieldsDetails: metafields(first: 5, namespace: "details") {
                edges {
                    node {
                        key
                        value
                    }
                }
            }
            variants(first: 5) {
                edges {
                    node {
                        id
                    }
                }
            }
            description
            priceRange {
                minVariantPrice {
                    amount
                    currencyCode
                }
                maxVariantPrice {
                    amount
                    currencyCode
                }
            }
        }
    }
`;

the result looks as follows: 

     ],
        "__typename": "ProductVariantConnection"
      },
      "priceRange": {
        "minVariantPrice": {
          "amount": "495.0",
          "currencyCode": "EUR",
          "__typename": "MoneyV2"
        },
        "maxVariantPrice": {
          "amount": "495.0",
          "currencyCode": "EUR",
          "__typename": "MoneyV2"
        },
        "__typename": "ProductPriceRange"
      },
      "__typename": "Product"
    }
  }
}

 Any changes to the price are being completely ignored, changes to everything else are immediately reflected within the API.
