Issue Summary

When the sprint name is customized, the sprint duration will be inherited in future sprints.
if you update the start or end date in one of the futures sprints, the behavior stops, and now only the custom name is copied

This is reproducible on Data Center: (yes) / (no)

Steps to Reproduce

1. Create a sprint
2. Update the name and select the duration
3. Create future sprints
4. Future sprints will inherit the custom name + duration incremented accordingly
5. Change the duration from the last sprint created
6. Create a future sprint
7. New sprint stop inherits the duration.

Expected Results

There is an FR to have the ability to automatically fill dates, so this shouldn't stop when you update the date or shouldn't start when you customize the sprint name

Actual Results

The sprint duration is copied from the previous sprint when the Sprint Name is custom.

Workaround

Edit the start date to stop copying the sprint range date.
