Product Page Optimization Data Discrepancy

Hello everyone,

I've observed a difference between the data in our main analytics and the data displayed in the product page optimization analytics for my experiments. Specifically, the number of unique impressions and conversion rate (CR) in the experiment doesn't match the number of unique impressions and CR shown on the analytics page.

According to the information provided, the Conversion Rate for product page optimization is calculated as the number of Total Downloads divided by the number of Unique Impressions. However, this calculation doesn't align with what we see.

Has anyone else encountered a similar issue or been able to determine the cause of this discrepancy?

Thank you
