Dataflows: Data Source legacy error

[luukov]

We are having issues with legacy data sources that have been used within creating an Dataflow in the PBI Service. 

Creating a dataflow and connecting to an source is working just fine, but once changing the data source (or adding additional data sources and/or deleting the old source within the dataflow) will turn out that every selected data source will be kept within the Data Source credentials setting page, and as the source for the Dataflow in the List View / Lineage View.

Expectation was that the old source was phased out on the Dataflow (cannot find it back anywhere in the Power Query steps), but is still there in the view...

Why keeping these old sources? And how do I get rid of these old sources...
Many thanks in advance

Hi @luukov ,

It seems that there is such a problem. I will try to find someone who is familiar with this to take a further look at this. I will post back if we have any conclusions on this topic.
