Erratic margin/padding in Avada post grid

#1

After an Avada update a while ago (not blaming Avada, probably just a conflict) the posts grid in masonry mode has been messed up. It appears to have interjected some bottom margin or padding after posts that include a featured image, but not the ones that don’t. It messes up the grid and just looks bad. Oddly I can’t see any margin or padding highlighted in ‘inspect element’ mode in Safari.

It’s happened on several of our sites that use Avada, but you can see it on the home page of forwardermagazine.com

Any ideas would be appreciated. I’ve tried disabling EVERY plugin and of course everything is up to date.
