Issue with Attributes when Importing New Products with Printful

I am currently using Printful to add new products to my Woocommerce store. When each (variable) product is loaded, the attributes that are loaded (color, size) are titled exactly how I have them set up within Woocommerce…but they are loaded as custom attributes. This results in me having to add the color and size manually for each product and attach it to every varying product separately (see attached).

This is heavily time consuming and I want to know what I can do so that what is automatically imported with Printful populates with the attributes set up in Woocommerce. Please advise.
