Ghost Datasource

Same problem as this one i think https://community.powerbi.com/t5/Integrations-with-Files-and/Unable-to-change-path-for-datasource-in-uploaded-pbix-file-in/td-p/2541/highlight/false

When I upload and configure this report https://gallery.technet.microsoft.com/PowerON-Power-BI-ConfigMgr-0cd61c5f to our on premise power bi (January 2019) I have a very strange issue, it shows me 2 datasource on the Data sources tab in the report server web page but i see only one in power bi desktop...

The first one is

pdms01ps1;CM_P01

 Probably a test when the power PI report was generated and as it is non existent in my environement i cannot schedule a refresh of the report...

Any idea ?
