It affects many products:
I also performed a rich results test, which gives this error:
Can you please help?
Hello @Grillo, the breadcrumb schemas have not been implemented properly. Here's an example of the proper schema I implemented in my site: https://search.google.com/test/rich-results?id=_tOFape5QF_xjk3KRF4ZPw
You'll need to define the list item properly like this: https://prnt.sc/xv55yk, which will solve the missing position error.
You can refer to my link and check out the schema codes for reference.
Other than that there are many schema missing fields in most of your pages that need to be filled. Once you add the missing info like SKU, reviews, etc. most of the errors will be solved or will be reduced. LMk if my solution helps
