Google Shopping information not updating through Shopify Product Import

[BMOLLOY]

Hey

I have added all my Google Shopping Product Categories and a few other Google Shopping information using the product Export/Import, but none of the added fields have altered. 

Fields I am trying to populate

-"Google Shopping / Google Product Category"  these were from the Suggest Google Categories e.g. Product > Product type

-Google Shopping / Condition: "NEW"

-Google Shopping / Custom Product: "FALSE"

There were no errors during the import, it was a CSV.
