Well, I am sorry for your loss, but as the bidding rules above say:
"Vote shares will be decided by the percentage of the amount you sent divided by the total amount sent in the actual voting period (2.4 hours). "
You have sent your bid in a round where the total amount sent was over 4 SBDs, whereas the total upvote value of the bot is around 4 SBD BEFORE curation. None of the bots have good payouts when the anount sent is higher than the upvote value.
