Analytics - Last Viewed Date Discrepancy

One of our premium customers (CPCMG) has reported a mismatch in the last viewed date between the article and the readers' section of the same article.

In our One stop article, on the article analytics page, Baskaran's account shows the last view as October 31st for this article. However, on the reader analytics page, the same account shows the last view as October 30th for the same article.
