There is definitely a problem with vote counting and comments (specially secondary & tertiary comments under a post).

Now, I have encountered an other problem since this post of mine:

(You may want to read the comments that follow).

Upvotes may not immediately reflect on a post despite the initial voting. When revoting, they may appear with a different percentage that you set during the revoting process. Occasionally, a message may appear saying, "Dismiss, you have already voted," especially if the percentage remains the same. Additionally, there are instances where you inadvertently vote on the same post at a different percentage.
