Even the release details have been copied and in case I try to delete the issues from Project B. I see that they also get deleted from Project A which is a live project.
So how to separate out the Sprint details, release details of issues from both projects.
I mean the project A export file was having field "projectname" which I changed from project A to project B. Now, I imported that file to project B. I guess since the import was carried out with csv having Sprint field and release field as well. So, it created similar fields for project B also. Further, I guess since the release and sprint were having same sprint id and version id. Therefore, the issues are interlinked in both the projects. Thus, in case I delete a sprint X for Project B which got imported from project A. The sprint X of Project A also gets deleted.
I hope you understand my problem now.
I don't understand what you've done, why, or what you're trying to achieve by doing it.
Some things jumped out as clear though:
You must be a registered user to add a comment. If you've already registered, sign in. Otherwise, register and sign in.
This does not sound like the way JIRA behaves at all.
Could you clarify something - when you say "project", do you actually mean "board"?

By Project I mean "Project" named "A" and "B" and the issues can be seen in both the project boards and on clicking left nav backlog also. In that view issues are coming based on the Sprints listed in Project A.

Your boards are set to include issues from both projects. You need to change those.
