How to solve loading problems in adding DICOM data

Hi everyone! I am new to 3D slicer, and I encountered some problems in loading the data. I wonder do I need to fix the code (which I don’t know how…). It would be great if someone can help! Many thanks!

The info here should help you get started: DICOM — 3D Slicer documentation

Series numbers >= 100 are all reprocessed images, reports, etc., which may not be loadable as images. Do you expect to have images in them? If not then you can safely ignore these series.
