Products page glitch

Hello! I’ve noticed something odd happening on my products page. Here is the link to one of the pages on my site where the glitch is quite apparent: http://www.cloakandcurio.com/the-craft-room/

It seems that some of my products are not appearing as they should when you first look at this page. If you click on next or page 2, and then click back to page 1, the products that were originally not appearing on page 1 finally show up (watch for the sock bunnies not appearing and then appearing when you click back and forth between page 1 and 2).

Can someone please explain why this is happening and how to fix it?

Many thanks!
