What version of dcm2niix was used for the conversion of your DICOM images to NIfTI? I think if you convert your images with a recent release of dcm2niix it will resolve your problem. My guess is these images were acquired using a new proprietary encoding method (e.g. zip2) that requires a custom kludge in the image conversion tool. If my guess is correct, the latest (1.0.20241208) version of dcm2niix will resolve your issue.
