Then I consider that the no,of the Total Likes that you received is NOT THE ACTUAL VALUE 
This mod bug is pretty old, it doesn't happen very often though, it's pretty rare, the mod developer hasn't updated the mod and fixed the bug yet, i'm not sure whether he'll ever do, I think it happens whenever someone clicks the like button and the animation of the button takes a delay to happen, then the user clicks again which I suppose causes it, however thank you for your report anyways, we'll look into it.
