I can see it double voted you, but the actual vote is the same due to rounding issues with Steem. I have switched nodes as Steemit Inc's node is basically unusable. This is also why Steemit.com is acting up with voting, commenting, resteeming, posting, and just even loading a page right now.
Okay but I just lost 3$ of upvote value compared to the 1st vote.
Let's forget it but it is a bit annoying (not only your fault but Steem's one obviously).
Take care.
I'm still trying to make sense of what happened, but we are using a private node right now while the primary steem node is acting up.
