On the "Next tag badge" panel of my Stack Overflow profile for C# tag, I see:
But, when I open the "Select your next badge" panel, there's:
I'm not sure which one is correct. But I believe that both displays should show the same counts.
The discrepancy is not due to a caching, I've noticed it the first time many weeks ago.
For these particular current counts: I have a single C# answer with 3 votes only in the last 5 days, last upvoted 13 hours ago (2015-10-12 19:30:05Z). So it should not cause the 5 votes and 2 answers difference.
I believe that the counters on the "Select your next badge" are correct and the counters on the "Next tag badge" are wrong, as I have:
Asked 1 non-wiki question with a total score of 6. Gave 90 non-wiki answers with a total score of 97.
Today (2015-10-16), the "Next tag badge" got bumped to 97/100. But "Select your next badge" shows 98/100 already.
