I created several invalid sprints last year. How can I delete or remove inactive these duplicate one

[Ashwini Leen A L]

A few months ago, I created future sprints with sequential naming. However, in early July, we adopted a new naming convention starting from Sprint 1 instead of continuing the previous sequence

Hello @Ashwini Leen A L ,

Good day! Welcome to Atlassian Community :)

You can 

1. Go to your Backlog view (under your Scrum board).

2. Locate the invalid sprint.

3. Click the three-dot menu (•••) next to the sprint name.

4. Click "Delete Sprint"

Thank you!
