Issues with the "like" button, loop count, and the time on each post

Issue: first, I have issue on the “like” button; whenever I disliked it and then liked it again, the number of likes usually go to that same amount. Secondly, the number of loops( not in my stats) sometimes stay the same. And thirdly, the numver of hours and minutes on each post tend to fade away, which you see at the bottom left corner near your username.
