Dear Sir,
As more information is required to check the issue related to content not getting green. Kindly request you to raise a SOLAR support ticket for this issue with all the information.
We will be checking the issue and will respond soon.
Kindly note that the reconcile button should not be used for such issues. The error " Reconcile Failed Learner marks are same or greater than uploaded marks." is just a message indicating that the marks are right for the respective learner and that no improvement has been found since reconciling.
