You may face an issue where the student tracker is not filtering results as you want. Specifically, when filtering using a decimal number, the results given are not correct. However, this is not the case for integers, where the results are fine.
This issue was due to a defect in the backend services and was solved by the engineering team on 31/Oct/2021. If you face it again, please create a support ticket and attach reproduction steps, a screenshot of the filter, and an example student where the issue appears.
This issue was already escalated in JIRA: SCLOOPW-25765 and solved by the engineering team. The problem was a defect in the backend services: Given the percentage value is parsed as int, and if there is a decimal point inside then it falls back to the default value, which is zero. So the input value was updated from int to double.
This issue should not come up again, however, if it does, please escalate it to the engineering team along with all relevant information and reproduction steps.
