The exact status of the pull Request is not getting synced in Jira by using Github for jira plugin

[Sunilkumar k]

Hi,  

Iam using the git hub for Jira Plugin, I have configured all the organizations and repositories accordingly, but I am facing the issue with one pull request that is I have raised the pull request and merged the pull request into master branch, but in jira the status of the particular pull requests is showing as open, but if i open in github it is actually merged, please help me in resolving the issue.

This issue is only for one particular pull request, rest all the pull request's are working fine.

Thanks in Advance !
