I know this issue is partially existing in other questions relating to tickets in other sprints displaying on boards but my concern is specific to the creation of a ticket.
Issue
When you create a ticket in project A, the sprint drop down field displays all available sprints from Project A, Project B, Project C etc.
Expected behaviour
Creating a ticket for a project should only be able to be added to a sprint in that project.
