Discrepancy in Apollo.io API Results vs. Frontend: Seeking Insights

Hi All, I have a question regarding the integration of Apollo.io with Clay. When I search for people in a specific company through Apollo manually, I get 13 results. However, when I use the API call in Clay, I only get 9 people returned. Has anyone encountered this discrepancy between the Apollo frontend and the API before? If so, do you know what causes the difference in the number of results? This has become a problem as we are facing this issue in multiple situations, and we are losing out on reaching out to potential contacts in a company. Thank you in advance for your help!
