Change name of Power Pivot table created with Power Query

I added a table ("Parameters") to the Data Model using a Power Query (with the option "add to data model" checked in the "Load To" options"). Due to circumstances (see "Details" below) it's called "Parameters 1" in Power Pivot. I now want to change the name in Power Pivot to "Parameters", but it says to change that in the Power Query. However, I can't find anywhere in the Power Query where to change the name of the table in the Data Model. Everywhere I look, it already says "Parameters".

Does anyone know where I can change this?

(Details:

I had a dynamic Excel table named "Parameters" which I added to Power Pivot using the Power Pivot option "Add to data model".

I then decided it would be better to add it to the data model via a Power Query, which I did. In the "Load to" options I checked "Add to data model".

I then had, logically, twice the same table in Power Pivot, one named "Parameters" and another "Parameters 1". I updated my DAX formulas to point to the new table ("Parameters 1"), and deleted the first table ("Parameters"). So far so good. But now I can't change the name of the table in Power Pivot...)
