There are a few possible reasons for this:
  • You may have listed the same constituent more than once in an upload. So even if you have 3 rows in your upload for Jane Doe, only one Jane Doe record will be updated and listed in the summary thusly.
  • If the update did not actually change a record, the record will not be listed as having been updated. So if you upload Jane Doe with no new information, Jane Doe will not be counted as having been updated.
