Can you provide the url of one of the pages that it says was affected? That shouldn't be a blocked resource, so I'll have to look into it further.
If you click on the blocked resource report it should show you why it was blocked and how to unblock it. That information would be helpful when looking into it.
It may not matter... this particular blocked resource should only be used when someone changes an option in the list. Since the google crawler shouldn't be doing that, the fact that it is blocked may be completely inconsequential and could be ignored since it won't affect google's ability to properly crawl the page.
