What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question

  3. Your voice helps shape the way Stack Exchange operates

This question already has an answer here:

Today I downvoted an answer so it went from 0 to -1

But I realised it was by mistake so I upvoted the same answer again but this time the value went up to +1.

I was expecting this to be zero.

I have attached the image.

Vote Up/Down


When I refreshed the page it came back to 0 again.
