ProfessorAs a general troubleshooting test I suggest you look at the DataSource (Office365_Reports_SharepointOnlineSiteUsage) in Settings > LogicModules > DataSources, then use the Test Active Discovery button. Check what it shows for instances there and if the names look correct. If it shows correctly there then I would just delete all the instances then get Active Discovery to rebuild it. Note that this will cause you to lose any historical data for sharepoint site usage, but since it sounds like it never worked until just now, so I assume that is ok to do. If the test still shows GUIDs then you might need to dig into the powershell code or work with LM support if it's not by design.
