Fix AMP Pages Issue in Shopify

I'm a store owner at 'guteszeug.ch' and I've noticed that some of our product pages are generating weird AMP pages when accessed via Google organic search. I'm uncertain about what could be causing this as I haven't made recent changes to the store, nor do I use any AMP specific apps or plugins.
Please find out whats generating these AMP pages and how to stop any amp pages being generated
