If it can help in your investigation, I believe @remlaps has a personal trail bot with the lead upvote being triggered by @cmp2020-lite. I have only ever seen this glitch occur when this account upvotes and triggers the trail. In fact, all of the accounts on the trail that have a >$0.00 value somehow become zero, which as you can see in the above example, those accounts are now showing the true value of the vote.
