The "Content Reward"?

Looking over at my wallet after cashing in my latest earnings a short while ago, I saw this:

So after two overlapping screenshots of History, we see
0.002+0.002+0.001+0.001+0.001+ 0.003 HP+0.659 HBD + 0.165 HBD + 0.356 HP + 0.005 HP + 0.003 HP + 0.001 HP and then finally "claim rewards" 0.23 HBD+0.735 HP.

Now these values since the last claim add up to 0.824 HBD + 0.01 HP but the claim reward button shows says 0.165 HBD + 0.375 HP:

Is this a display problem of some kind? These numbers do not add up to the rewards available for claim. The results as shown here on ProofofBrain.blog are the same on Hive account@ecency ecency.com (#ecency). On #peakd (https://peakd.com) these reward values are not displayed at all in the transactions. If not counting the "content reward", it's perfect. So what is "content reward"?

Hive Reward System

The rewards for the particular post is 0.66 post when I opened it. Yet the "content reward" reads 0.824 HBD... This leaves 0.33 HBD payout, half of that is 0.165 HBD and the other half is the other 50%. So why does reward read as 0.824 HBD?

The content reward value seems redundant here but I guess it is supposed to mean something. It is exactly 5/2 times the value of the author reward... Curious...
