I am experiencing an issue in Copilot Studio where, when I upload my dataset in chunks, the AI provides precise answers but inaccurate row counts. For example, if my dataset contains 50 rows, it might return 40 rows, does same in bigger data and on re-asking, it provides a different count. The data itself has no null values, so missing data isn't the issue. How can I ensure consistent and accurate row counting when handling large datasets or in chunks?
