Custom meta attributes only PRO?

Hello team,

I am working on a website with over 2000 references in stock, so I created and imported a CSV with all the items. There are around 8 custom attributes created for these items. All custom attributes were created automatically when importing the CSV file.

The attributes were not created and won’t be seen in “Products -> Attributes” but they OK can be seen when checking any product, that’s not what I expected but I don’t mind since it works.

Now I was looking for a good Product filter plugin that would let me show and filter these custom attributes. After testing some, I thought this plugin was going to deliver!

But I can’t seem to make it work so far… When I am creating the Attribute filter inside the plugin, I only see option “Custom meta field Pro”, but in the docs of the plugin it says “Custom meta field”… So I am assuming this feature became Pro-only, right? I can’t seem to make it work like this.

I know many plugins would have let me do this if the Attributes were created in Attributes but for some reason they were not and there are too many variables to make it manually so I am forced to do it this way. My custom attributes are only seen when going inside each product. When I inspect some of these attributes in a product, I can get their “class”, which I guess is what I need to put in the “Custom meta field” (if it allowed me), like :

woocommerce-product-attributes-item woocommerce-product-attributes-item--attribute_acabado

My custom field slug would be “_acabado” right?

Would the PRO version do what I want? Is there any other way to make this work?
