Portfolio Page Layout Issue

Hi! I’m having a weird sorting issue, or layout issue on the portfolio page. http://bluemoongiftshops.net/shops/ to see what it’s doing. If you scroll down to where you see the shops Crystal Coast Impressions and Crystal Creek Jewelry you will notice that they are for some reason skipping 2 spaces between them. Same with Island Girl Art and Island Girl Glass (which you will not see on the page right now) but no issue with The Carousel Collection and The Carousel Collection II. It seemed the first word being the same has something to do with it but not sure what the deal is. Any suggestions? Out of curiosity I made Island Girl Glass a draft and the item following Island Girl Art is still in the same off spot and now another random one is out of place. Please let me know what you think is going on. Thank you!!!
