Cannot close the Sprint even though jira tkt is closed.

Cannot close the Sprint even though jira tkt and all of its subtasks are closed. No other option seen (screenshot). 

I donot want to remove tkt from the sprint. 

Kindly advice?

 I was able to resolve this issue.  I had to go to all apps board and found a subtask, that was not assigned to any parent tkt. Somehow this subtask was separated from its parent tkt. But system was still considering it as a subtask of that main tkt in current sprint. Deleting the subtask, enabled me to close the sprint.  Finding that "orphaned" subtask led me to see that it didnot have a parent tkt linked.
