need help with rich snippet „itemReviewed”

Hello again

When I try to check if rich snipped working like it should i have one error ( please check the photo attached ).

So if you go into URL
https://search.google.com/test/rich-results?id=VBcuf4yUYwWNshBeD4Znfw

I have got 2 error
1)Type of object is not valid with „itemReviewed”
2)This element does not works with opinion

I read that I need to go into component => general=> Include average rating only  (please check photo attached )

Please let me know if You can help me with that error. If it not possible to fix it maybe the best solution is to remove it from source code because it takes extra byte to download ?
