I don't know if this is just happening with me or others are facing the same issue and this is not the first time I'm having this issue. The issue is that on 1 Post I had a pending reward of around $9.14 but at the time of the payout the reward was like $7.40. I'm attaching some screenshots below for proof. If anyone is facing the same problem please comment and who knows what causes this please explain.
Let me suggest you go to this post for a great explanation on how payouts work:

Given the recent price volatility, you could see changes in the actual payouts given the average used for the STEEM portion. In addition, I have learned from @brandonfyre that some applications also take up to 25% of your rewards if you use them to post. I see that you used dMania and that could be why you have this reduction as well. Here is a post that explains that as well:

well the actual payout was around $7.40 but given the prices going up the payout went to $9.14, but the payout was the same amount which was the actual payout at the beginning. however will have a look at the post you suggested
