because when you made that post initially it only mentioned 2 tweets, 2 post + likes and 1 comment
so when I saw the post, I calculated the rewards based on what you wrote then, you obviously afterwards have added extra tweets to that post
luckily Google cache hasn't refreshed, so was able to make a screenshot of your initial post
I will recalculate for week 2, but please don't make a post at beginning of week and then afterwards go change it, there's no way to keep track of such changes
