I have joined a project recently were at Sprint 99, they started all over again with numbering (Sprint 1). So when I create a new Sprint e.g. Sprint 3 (which already exist) and I start the Sprint, than all the old User Stories and Issues appear (status done).
Is there any recommendation how to best coop with such problem, shall I just go to Sprint 101, I don't have the option to create a new Project.
Thank you for any advise.
