Possible Solutions:

1. Verify Minimum Isolate Selection: Ensure that the minimum number of isolates selected is sufficient. If it is lower than the actual number of isolates present in your dataset, the antibiogram report may display empty or unavailable data.
2. Check Date Ranges: Review the "Records From" and "To" date fields. An incorrect date entry in your dataset, especially in the isolate calculation logic, can prevent the report from being generated accurately.

Double-check these parameters to ensure that your dataset aligns with the expected input requirements, and all relevant information is correctly formatted and within valid ranges.
