I have 9 items in a CMS gallery which is formatted in columns. When I load the page, sometimes only 3 or 4 of the CMS items will load. Other times maybe 8 or all 9 of them will load. Every time I re-publish the site, the number seems to be different.
Whenever CMS items don’t show up, I can still see their 1px shadow in the location where they should be. (See screenshots below)
On another page I have a similar CMS gallery in the same masonry (text columns) style, but it works just fine.
