Time Card Summary with Drill Down Detail Report

Can there be some improvements to this report? For instance I've needed to go back a couple of years to determine how many children attended during a specific year, however, when doing so it generates the report with children who weren't in the specific classroom filtered during the specific date range listed. For example, I need to look back at how many grade school children attended in 2022 & 2023 however it includes children that weren't even in school during those 2 years - they were in preschool - but they are in Kindergarten currently. I'm assuming it includes these children because that is their current listed classroom. This isn't helpful when I need an accurate count for specific prior years for specific classrooms. Please let me know if there is a better report to use of if there are ways around this issue. Thank you!
