Something is going wrong with my reputation

Question

Whenever I gain reputation, I get 4 additional reputation. See this picture:

This picture is captured when I gained reputation by +5 (for upvote on my question.). Before I gain +5 reputation, my reputation was 2,211. And after I gained +5 reputation, my reputation became 2,220 (as shown in the above picture). But when I refresh my page the real reputation is shown like this:

So the problem is minor. But why do this happen? I suspect this issue might be related with this issue.

EDIT: I do not face this issue in the case of downvotes.

We love to instantly notify people of the positive activities that happen. When somebody loves the things you do you are instantly notified by a reputation increase. The negative - well, you get to know about it but it's not as instant. We assume those with a negativity need to have a bit of time to evaluate their decision before that choice is made known. We also try to protect people who down vote from being discovered.
