# A recurring shift edit did something unexpected

**For:** Manager
**You'll need:** Nothing.

You changed one Tuesday shift in a recurring series — and either every Tuesday changed, or only that one did, or the series split in half. {{ app_name }} asks you which scope you wanted; the wrong choice produces surprising results.

## What the scope chooser does

When you save an edit on a recurring shift, {{ app_name }} pops a modal with three choices:

- **'This occurrence'** — change only the shift you opened. Every other occurrence stays the same. The series remembers this date as an exception.
- **'This and following occurrences'** — split the series at this date. The original series ends just before today; a new series starts here with your edits. Past occurrences are untouched.
- **'All occurrences'** — regenerate the entire series from your edits. Past and future occurrences both change. Any **'This occurrence'** exceptions you made earlier are preserved.

## Check three possibilities

1. **You picked the wrong scope.** If the change was bigger or smaller than you wanted, undo it: open the same shift again and apply the opposite scope (or fix individual children with **'This occurrence'**).
2. **The change was a date or time change in a weekly pattern with multiple weekdays.** {{ app_name }} shows a different modal for these — **'Smart-replace this weekday'** vs **'Shift the entire series'**. Re-open the shift and look closely at the modal copy.
3. **You meant to edit one occurrence but the modal didn't appear.** Non-recurring shifts don't show the chooser. Make sure you opened the recurring child you intended; the parent series and standalone shifts behave differently.
