One or more of your ad Labels/Buttons/Images are not inside the AdMobNativeAdLayout component in the screen design.
Place your ad UI (labels, images, button, etc.) inside that layout only, not outsidi it.
Correct structure
VerticalArrangement (AdMobNativeAdLayout)
├── Label_Headline
├── Label_Body
├── Image_Icon
└── Button_CTA
Add vertical arrangements, then place your AdMobNativeAd component in that layout
