Research Prices Tool not displaying accurate shipping information

[mycoenvy]

The "Research Prices" tool on the "Manage active listings" page is displaying some listings as charging $0.00 when they are charging for shipping (see attached pictures of a random example).Item shows shipping as $0.00Shipping is actually a calculated rate

This has caused me to make decisions about pricing on my listings which affected my final sale price; and therefore eBay's fee as well.  

Does anyone know why the shipping displays in this way?  

Thanks
