Unable to upload the Benefits Enrollments through Excel Benefit uploads?

Summary:

Content (please ensure you mask any confidential information):

I'm trying to upload the Benefits enrollment through spreadsheet loader but I'm getting an error. I'm not sure how to upload them.

If a plan is automatic, should we skip those lines?

If a plan is explicit but not changed , then should I put them in the line so that it gets updated or should I put both Plan enrolled and plan disenrolled from.?

Also can we upload multiple employees if the life event occurred date is different in the same file.

Should we give the close life event at each row or at the last row?
