Setting Dictionary seems to have no effect

In explorer, I see:

Even though in Orthanc.json, I set:

   "Dictionary": {
        "0019,1008": [ "CS", "Private_0019_10xxType", 1, 1 ],
        "0019,1009": [ "LO", "Private_0019_10xxVersion", 1, 1 ],
        "0019,100A": [ "US", "LocationsInAcquisition", 1, 1 ],
        "0019,100B": [ "DS", "SliceMeasurementDuration", 1, 1 ],
        "0019,100C": [ "IS", "B_value", 1, 1 ],
        "0019,100D": [ "CS", "DiffusionDirectionality", 1, 1 ],
        "0019,100E": [ "FD", "DiffusionGradientDirection", 1, 1 ],
        "0019,100F": [ "SH", "GradientMode", 1, 1 ],
        "0019,1011": [ "SH", "FlowCompensation", 1, 1 ],
        "0019,1012": [ "SL", "TablePositionOrigin", 1, 1 ],
        "0019,1013": [ "SL", "ImaAbsTablePosition", 1, 1 ],
        "0019,1014": [ "IS", "ImaRelTablePosition", 1, 1 ],
        "0019,1015": [ "FD", "SlicePosition_PCS", 1, 1 ],
        "0019,1016": [ "DS", "TimeAfterStart", 1, 1 ],
        "0019,1017": [ "DS", "SliceResolution", 1, 1 ],
        "0019,1018": [ "IS", "RealDwellTime", 1, 1 ],
        "0019,1025": [ "DS", "RBMoCoTrans", 1, 1 ],
        "0019,1026": [ "DS", "RBMoCoRot", 1, 1 ],
        "0019,1027": [ "FD", "B_matrix", 1, 1 ],
        "0019,1028": [ "FD", "BandwidthPerPixelPhaseEncode", 1, 1 ],
        "0019,1029": [ "FD", "MosaicRefAcqTimes", 1, 1 ]
    },

What am I doing wrong here? I am using orthancteam/orthanc:24.10.2.

I figured it out. 0019,0010 was already set by the modality to "SIEMENS MR HEADER". I had to add that string as the 5th element in the array on each of those lines, e.g.

"0019,1027": [ "FD", "B_matrix", 1, 1, "SIEMENS MR HEADER"],
