Feed “product_type” data reversed order in the plugin update 6.4.0

The order of the categories listed in the product_type attribute suddenly reversed with the update to 6.4.0.

Prior, it was of the pattern “Sofas > ABC Collection” and now is “ABC Collection > Sofas”.

Was this an intended change? It broke all of my client’s Google Ads which were Product Grouped by the top level type “Sofas”.
