AMP reporting not working

Hi, when I added my GTM and GTM AMP container to the plugin instead of the GA code, my AMP tracking seems to have stopped. I no longer see AMP pages being tracked inside GA. Am I doing something wrong? https://www.pennbets.com/paypal/amp/ for example here is my AMP traffic since I installed the plugin https://i.imgur.com/GY8RJUo.png
