@Samith10 It looks like you included some extra commits in this one. I think perhaps you're just missing the step that when you've completed a PR you can do:
$ git checkout 2.x
then make a new branch for your next issue:
$ git checkout -b ELY-2829
and this won't include any prior changes and you can proceed with fixing the issue, committing and pushing the changes.

To add to what @luck3y said, you can then take your last commit from this branch and apply it to your new branch as follows:
git cherry-pick <commit-hash>

Seeing how this is the relevant commit, you would do
git cherry-pick e1d02f153d7d96b1c6f61c216b86c7df7606c9c9

That way you don't have to redo everything :-)
