Modul Google MerchantCenter - no Shipping Costs

Hello,
Im using eFire Google to push my products to the Google merchantCenter. The export works pretty well, there is just a problem with the shipping costs. If a product has no shipping costs (0 EUR) google doesn’t show this in the listing. The shipping cost information is just missing. I saw that Google lists the information “no shipping costs” by other shops / products but not by my shop.

I have insert shipping costs of 0 in Oxid eFire. Do I have to add anything else?

Best

Hello Dominik,
We use two filtered sets, on with the products that have shipping coasts and on set without. Normally this works fine for us.

maybe it would be a solution to add default shipping costs in google merchant center
