Sorry I did not see this post and question.
Are you still experiencing issues?
My recommendation is to either upgrade to the latest SR (2.0.6?).
Or, remove (or rename) the existing Operations Monitor and import the Operations Monitor again from Qlik\Sense\Repository\DefaultApps. You might consider removing all of the QVDs in the Qlik\Sense\Log folder - these are created by the Monitoring Apps and will be created again with a reload.
Sorry for the long delay in a response!
