Missing items usually lack a usable source date or were not selected. Duplicates usually come from importing the same source more than once or combining manual and imported records.

Checks to make

  1. Confirm source access in iOS Settings.
  2. Open the source app and verify the birthday, event, or reminder has a valid date.
  3. Repeat the import and select only missing entries. Use Select All only when every visible result is wanted.
  4. Compare names and dates before saving.
  5. Delete a single duplicate with the normal list delete gesture, or touch and hold a row to select several duplicates.
  6. In selection mode, select the records to remove, optionally use Select All, then choose Delete and confirm.

What the result tells you

  • Imports are copies, so there may be no permanent source identifier visible in the app.
  • Changing a source after import does not necessarily update the copied record.
  • Exact same-name and same-date records are skipped when possible, but variations in either field can still create separate records.

Before trying again

  • Import in small batches.
  • Standardize names to make duplicates easier to spot.
