How can I fix double rich snippets and missing information on my products?

Hello,

I’m writting to yo beacuse I have problems with my rich snippets on my Shopify store

Some of our products have double rich snippets for example :

That should come form an app we installed and uninstalled but we are not sure. Could you help me ?

Another subject : our rich snippets doesn’t appear well : we have our review and number of reviews but we don’t have the price and the availability in our stock. We have TrustPilot for our reviews and most of the apps for rich snippets doesn’t work with it. I don’t know how to solve that problem.

Thanks in advance for helping me

Damien
