Upvoted and favorited images aren't showing up in my upvotes tab.

So, I upvote and fav a bunch of pictures. I then go to my upvote and fav tabs, but less then half the pictures I upvoted appear in the tab. I exit out of my browser, log back in, and it’s still not there.
 
And yes, I know that the pictures in your upvoted tab go by post date. All the pictures I’m having problems with were posted in the last 2 days.
