Counter not accurate.

Hi all,

My counter for Facebook is not accurate. When I first installed the plugin, it said 70 something shares for Facebook. And my site is not visited nearly that much. And every time I post another post, it starts the newest post with what that last newest post had. It just keeps counting up it seems. The previous posts seem to work ok.

My website is a webcomic. So for example, if I post Comic #1, it will show 77 shares for no reason for Facebook. So if I share that comic, it will then say 78 shares. And if I post Comic #2, Comic #1 is replaced by Comic #2. And if I share Comic #2, it will then show Comic #2 having 79 shares. Why is this happening? Please help.
