Masonry blog viewing issues

Hi everyone - 

I am working on this new site - https://leftbankco.squarespace.com/journal

and am having issues with the Masonry blog view. This is how the page is viewing at the moment in my incognito browser when the page loads. The entries are overlapping and not viewing correctly. 

The issue seems to be fixed when you adjust the page size or change the size of your browser window. I am wondering if there is anyway I can get the blogs to load properly straight up?
