As the page title says, you should save the page for future reference in case anything untended happens.
You may need to delete the discovery logs and re-run discoveries for them to be viewable in the GUI. To delete the logs go to menu → Admin → Database → List Tables → Discovery Log → DELETE. No device data will be lost, just the discovery log data, which will be repopulated the next time the discovery is run.
Please save this page for reference
