Calibre not downloading book covers.

Hello everyone, so for some reason Calibre will no download from sources other than Goodreads or Kindle HD, despite having all of the sources that I wish to use checked. Please note that before, when using the Google Images selection a LOT of images were displayed. And no, I'm not IP banned, I did read on another thread that that was the culprit for someone else, besides, I have more than just Google selected, and I'm only getting results from Goodreads. Otherwise, if that's unchecked, I don't get anything. Removing the ID's in Metadata does nothing, like in regards to ISBN and such.

Please see screenshots to see what I am having to experience. Any suggestions? Thanks.
