Product Attribute Value has only one localized value. It name "Name". You need to add this "Name"  in mapping.

"Localized values - Product Attribute Value"

You need to set
Key,
ProductAttribute   - the plugin will sue this parameter for looking for product attribute
ProductAttributeValue   - the plugin will sue this parameter for looking for product attribute value
LocalizedValue  
LanguageID

One moment.
Do you want to add localized values for
Product Attribute Value
or
Product Attribute?

Attribute
Do you use the primary attribute name?

/// <summary>
    /// Represents a specification attribute type
    /// </summary>
    public enum SpecificationAttributeType
    {
        /// <summary>
        /// Option
        /// </summary>
        Option = 0,

        /// <summary>
        /// Custom text
        /// </summary>
        CustomText = 10,

        /// <summary>
        /// Custom HTML text
        /// </summary>
        CustomHtmlText = 20,

        /// <summary>
        /// Hyperlink
        /// </summary>
        Hyperlink = 30
    }


You forget about option value. Each specification attribute must have option and nopcommerce uses this option for mapping specification attributes.
Try it
sku  Name  Type  Attribute  Value Option
XYZ  FARINA   20 Ingredienti  <p>Lorem ipsum</p>  OptionName

and remember about separator.
You want to add HTML custom value in the specification attribute but you need to add option for mapping.

Please try the new release again

Did you create the custom tracking code (the type Custom)
