Power BI Desktop - Application Bug in Data Source Settings

Hello, I identified a bug in the screen Data Source Settings -> Change Source.

When I click in this option open a new windows window tab and not happen how you  can see in that screenshot.

I tried to do the same operation in two different computers but i'm still facing with this trouble.

I just can change the source from PowerBI Semantic Models in live connection as I know.

Anynone had the same trouble ?  In fact, I really need to change this data source.
