Hi @Anonymous 

Is your data source just these two tables ? Or are there two additional tables on top of the original data ? Do you get this error reported if you use the previous version ?

Resolved:

Did talk with MS suppport,  looks like this is a issue in Feb release,  It was solved by installing the old dec release and also clearing the logs in settings//diagnostics and hard uninstall Feb release
