In the certificate module settings there is an option to set the required course grade.
In one of our course, the required course grade has been set as 60% (the total mark=250 for that course). So, certificate should be issued only when a student scores 150 or above in a grade of 250. But, we observed that its taking the total marks of the course as the course percentage and issuing the certificate with '-' grades even if you score 65/250. We have set no grade letters in case the percentage is below 60% thats why the grade is coming as '-'.
Please let me know how to solve the above issue.
