Need a Shopify expert to fix bugs

I have some errors on my Shopify store. It's reported in search console. A misconfigured schema is causing the trouble. I'm unable to locate the pages inside this theme. Not an usual theme. If you know your way around Shopify themes, then it's a easy quick buck for you.

PS: I will not share the Shopify login credentials, you have to fix it via TeamViewer. If you don't agree to this, please don't bid.
