We have issues as part of a sprint which is moved to "Done" status in green and the resolution shows "Completed" in that sprint. The issue is also moved to the last column in the board where "done" status is mapped to. Still the issue is a part of every sprint created after that, till date. This doesn't happen to every issue in the sprint but to a handful. Trying to figure out any possible link between the issues but couldn't.
Need help on any other possible reason due to which this might happen.
