Thank you very much for the feedback! Can you switch the machine type to "Ultimaker (volumetric)"? We have printed dozens of parts with a volumetric calibration, so this should really work well.
Non-volumetric calibration is kind of outdated and not recommended anymore. For a quick guide, the Howto of Paul

Please feel free to give me more feedback about your findings, either here or as support ticket.
Best wishes and happy holidays,
