Very weird one here.
I have two projects: [A] and [B]. I have created a Scrum board on each project; each board is based off of an existing saved filter; each board uses a unique filter. By all accounts, these boards are unique in every way and do not share anything with one another.
However, one of the sprints built for project [A] are appearing in the backlog of project [B]. This wayward sprint is displaying with 0 issues, but if I delete it in project [B] then it deleted in project [A] as well. Project [A]'s backlog looks fine and correct.
I have tried recreating both project boards and re-saving their respective filters but the problem persists.
Has anyone experienced anything like this before? Any ideas about another setting I could check? Thanks in advance,
