Spaces between posts using inked Blog

Hi, I’m using the Inked Blog widget to put blog posts on various pages on my website. However there seems to be a random space between some of the posts while others have no space between them and I don’t know why it’s doing that.

Hope you could help.

Thanks.

Here is a link to my website so you can see the problem.
