Correct .. It looks like the votes are being casted correctly and that it is a back-end reporting issue.
reference: I upvoted this post https://steemit.com/steem/@au1nethyb1/reducing-friction-for-critical-mass-adoption-of-steemit here 1129416 61c4d202e0f422af33ef7927bc18ff7145234128 vote {"voter":"jsc","author":"au1nethyb1","permlink":"reducing-friction-for-critical-mass-adoption-of-steemit","weight":10000}
but the UI shows that I down voted, the get_content's active_votes[36] === {voter: "jsc", weight: 0}
