Hi Clayton,
Really sorry for the delay reply due to festival time here. We are back to our full day working now.
The top are set by the masonry js to on the fly to manage the spacing.
Regarding the above fix i sent to you. That should work. I have tested that here and it is fine. Or can you send me your wp-admin details at info (att) masonrylayout (dot) com ? I will fix that for you.
Thanks
