Reputation bugged?

I was looking at my Tropical Island map..
And I found out that I can see my reputation on that post by clicking on my own reputation button.
I clicked on it to test out of it should be possible to give myself reputation, however I found something weird.



I'm wondering how it is possible that I have only 2 reputation while I have already more at one post.
Even when I try to give someone else reputation it doesn't count at his reputation.
Am I understanding something wrong or is this a bug? - Please explain it to me. ???
