To fix the immediate problem, time fields need to be in the format “HHMMSS.FFFFFF” so 14:47:47 needs to be changed to 144747.000000 (see the TM field at https://dicom.nema.org/dicom/2013/output/chtml/part05/sect_6.2.html)
In your original file this is the field AcquisitionTime.
You should also upgrade your Slicer if possible as 5.x is better able to handle non-compliant DICOM files.
