Hello @salah.elfarissi, thank you for reporting this behaviour. I think I was able to reproduce the issue in FME Form 2025.0 & 2024.2.3. Moving forward, we can refer to this issue as FMEENGINE-86343. I assume this image is the output of a SchemaScanner? If so, to workaround the issue for the time being, you should be able to get results by using groupBy on fme_feature_type in the SchemaScanner. Let me know if you have any questions or need help applying a workaround. Happy to help, Kailin.
