Hello @Nate_Sheridan,
You can only offset the posts in the Looper Provider. When using the default WordPress Loop, you cannot offset it.
To get your issue, resolve, do not use any Looper Provider in your archive layout. Use two Looper Consumer. The first one which displays the hero post, the Looper Consumer item setting is “One”.

The second Looper Consumer can have the “All” items which will display the remaining post items:

If this does not work, please provide us access to your site so we can check your archive layout settings. You can create a secure note in your next reply with the following info:
– Link to your site
– WP login URL
– WP username
– WP password
– WP Administrator Role
- Confirmation that we can access and make changes to your site

Best Regards.
