It seems the AI placeholders are rather incompatible with this grid layout. In order to resolve this issue in the most effective way, I recommend disabling the AI placeholders by creating a new rule in the 'Disable Ads By Page' section.
You'll want to create a rule in 'Disable Ads By Page' under the 'Ad Tester' tab. You'll want to change the rule type to 'directory', enable the 'disable all positions' option, then place /page/
as the directory path.
You'll do this again, but this time keep the rule type as a page, disable all positions, and place /
as the page path. This will disable the AI placeholders on the home page.
Once you have disabled AI placeholders in the /page/ directory and home page, you can now proceed to create your own placeholders on the home page using the Ezoic Chrome extension. With this, you can set up the placeholders to show outside of the grid boxes. If you don't already know how to use the Chrome extension, check out this useful article!
