Bulk Upload issue

Upon loading of the spreadsheet, the report stated that it won’t import the media asset column and the individual ID column. However the “Import Overview” tells me that there are 19 columns in the import, which is correct, including the 2 types mentioned above, listed separately in the report as “not imported” .

Update on this issue. I’ve just checked and the metadata did get uploaded, not sure how since I did not proceed past the review of the Import Overview report. Now I’m trying to upload just the images, without a spreadsheet, since those did not get uploaded. I’m not clear on how to do that without causing issues in the system
