Problems since wordpress and avada update

Using the latest version of wp and the same of avada

Since updating, using this plugin creates a huge gap between posts on my archive pages. The top few are spaced correctly, but those towards the bottom half of the page all have a huge gap under. Disable the plugin and the gaps vanish. The gaps aren’t affected by any other plugin.
