I had the same problem – which is why I found your post. I finally found a solution:
Get the “WP Facebook Like” plugin – it has a setting for priority placement after posts. Easy to work with and solves this problem.
Other search phrases I tried without success are listed here to help others find this solution:
“cool author box” edit
share this after post before author box
fb like share position
hack cool author box
hack addtoany position after post
Sorry I have not tested this with LinkWithin or Follow, but hopefully this offers a useful option.
