product_type_type wrong attribute in Google Feed and missing main image

Here is a sample item from a Merchants feed of my site:

<item>

<g:id>69971</g:id>

<g:title>XPRO edzett üvegfólia iPad 10,2" (7.-8.-9. gen.)</g:title>

</item>

As you can see the product_type_type is wrong definition (I used the built-in option).

Also if I select Main image as the image_link it renders the placeholder image in every product so the feed would become useless. I use the Additional image 1 as the temporary solution but this is bad solution because if there is no product gallery in one product it doesn’t add anything into the image_link attribute.
