I tried creating a service desk for our existing project that we are using for support. I hoped that once the SLA calculation was done I would be able to see reports for issues we had solved in the past based on our current SLA goals. However it appears all our old issues are marked as breeching SLA and they are all grouped on the day I installed Jira Service Desk rather than the day they were actually reported.
I guess I have two questions:
1. What is going wrong that causes all our past issues to be marked as breeching the SLA?
2. Why are all our old issues not shown with the date they were created in the reports?
