Search Console Connector retrieve wrong page ranking for specific keyword

Hi Community!
I'm trying to retrieve clicks, impressions and page ranking for a set of keywords.
If I only pick clicks and impressions, the overall number matches to what GSC shows.
If I add, in the same retrieval, clicks and impressions are shown for just one page which is not the most important page for that keyword.
If I make two separate operations, one for clicks and impressions, the second for page, the result is that the retrieved page is again not the best in class.

Any idea why this is happening?
