Autoblog not pulling posts

I am unable to get Autoblog to pull anything from a feed from another site I have set up.

feed: kenfreire.com/feed

I am using Featured Images in RSS w/ Size and Position to insert image into the feed. The validation says that "size" and "srcset" should not be in the description or content:encoded. Is this an autoblog error or an "image to feed" error?

Thanks!
