Hi,
First, please go to Customizer AMP > Header > un-check on "Load AMP Auto Ads Javascript"
After that, check again the guide here:
https://support.google.com/adsense/answer/9261309?hl=en
Google Adsense auto ads will give you 2 codes, one code required to add it inside <head> tag and one code required add inside <body> tag
Let's add the code inside <head> tag via Customizer AMP > Header > Add Custom Code Inside <head> Tag
And add the code inside <body> tag via Customizer AMP > Header > Add Custom Code after <body> Tag
Best Regards,
