see your comment rn, it has 1 upvote (from yourself by default) and 0 dislike (so it’s not shown)
but in the screenshot I sent above you got 287 upvote and minus -1 downvote (making your total 288) which is mathematically correct but seems like an unintended behavior
for example this comment of mine normally have 9 upvote and 2 downvote (which is shown as a positive integer 2, not negative), making my total upvote 7
or make you look like a stand user
