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.
  4. Compare names and dates before saving.
  5. Delete duplicate diBirthday records only after identifying the correct copy.

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.

Before trying again

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