The ad unit is requesting ad sizes that are larger than the screen. This reduces monetization as advertisers eventually bid on the set less or even stop bidding on it entirely.
Step 1: Validate if this was intentional. Be mindful of Google Policies on ad placements:
Step 2: Open your Ad Manager account > Inventory > Ad Units
Step 3: Audit the sizes per ad unit and edit if necessary to remove unwanted ad unit sizes.
Step 4: Log into tools.monetizemore.com
Step 5: Open the relevant PubGuru Header Bidding configuration
Step 6: Audit the ad sizes you have configured per ad unit
Step 7: Remove any ad size that is incorrectly configured
Step 8: Save & publish
