When calibrating a tool using the "IGT Navigation Tool Calibration" plugin, after performing the steps of initialization, tool tip calibration and tool axis calibration, "Save Calibrated Navigation Tool" is clicked.
When loading the calibrated tool, the "Tool Axis" coordinates remain unmodified, showing (0,0,-1).
The same happens when saving the whole tool storage with the previously calibrated tool.
The calibration process was tested on T23587-ImplementConverterForCalibration (mitk) and T24575-CreateUltrasoundCalibrationPlugin (cami-experimental) branches.
