Earlier today, I started a bounty (with 50 reps.) on my question "Show count of bounties earned or offered on Profile Page" and as per the rule it deducted 50 reps. from my total reputation immediately upon applying. Here is the screenshot of the same:
I was expecting to see "-50" reputation (in a Red box) gained since my last visit next to my total reps. in the REPUTATION box. But all I see is my new total reps. 2,090 (2,140 - 50). It does show a "-50" reps. that I have earned (in a Blue background box) next to my "reputation" tab.
When you get an up-vote on your post, you will see either +5 (for a question) or +10 (for an answer) reputation gained since your last visit in a little Green background box next to the total reps. (at '?' mark spot in the above screenshot) shown in the REPUTATION box.
So, is REPUTATION box only for displaying positively gained reps. since your last visit? Can anyone please explain?
