Why are non-indexed URLs appearing in my search console?

[Robert112]

Dear Shopify, We checked our site using the search console and found the following errors:
many non-indexed urls appear. Among them, those ending with the extension .atom. 
This negatively affects our appearance on Google. We did not ask for such a feature, please remove them.
In addition, several non-indexed urls containing the term "?pr_prod_strat" ​​are also displayed, which we do not know where they come from, please delete them as well.

Thank You.
