We are using the cloud version of Jira. I moved some issues from one project to another. When I went to my project those issues were grouped under the sprint name from the other project. I moved the issues the the correct location on my project and deleted that now unnecessary sprint on my project. Once deleted, it somehow changed the other project board and now they are connected. If I change the name of the sprint on my board, it changes on the other. Please help me with how to undo it.
