Getting inconsistent Facebook like counters on the site "Recommend this site" click buttons and "share this story" click buttons

I run several sites. I have a pre-programmed share and recommend FB Likes tracking buttons for site recommendation and article sharing on site. Both sets of code are shown below (do they look correct?).

Lately I've been told that Like counters fluctuate dramatically up and down in a short amount of time. The sharp increase and decrease is not 1 or 2, but tens at a time and within a few minutes.

Has anyone experienced this kind of result for your site from your programming efforts?

Are there any diagnostic tools to help explain these programming results?

Thank.

So I'm curious. Is there a place where I can look on Facebook to see Likes and Unlikes for http%3A%2F%2Fwww.mysite.com%2F

? Also, is there a place where I can look on Facebook to see Likes and Dislikes for http%3A%2F%2Fwww.mysite.com/article-slug/

? Where are these counters stored? Do they need to relate to something specific or configured on Facebook? Or can any website have these buttons regardless of whether the site url is defined in the FB empire?
