This is most likely because you are not telling Jira that the issues are "done".

To be done, they have to be in the last column of their board, and not have any open sub-tasks.

Hi @Priya Mishra welcome to the community. 

This happens when status is "Done" category, but the resolution field is empty. 
Jira understand that the issue is completed, when resolution is set.
