Instead of editing/updating your aliases on the viz, try dragging your Table Calculations to the Measures area of your data pane. This will allow you to give each Table Calc a unique name, plus it allows you to reference that calculation later in other views. Hope this helps!
This option is similar, but shows dragging and dropping into a new calculated field editor that is blank -- you can simply drag the Table Calc to measures (no special keys) and it will prompt you to give that measure a new name.
Thank you for responding to my issue.

I see this issue when I am applying custom colors to the measure names. For instance - I wanted to bold or change color or the last two rows by each Entity so I dragged measure names to the color marks and then cross tab shows 'along with text for each table calculations
When I didnt apply color to measure names - cross tab shows data like below which is what I want...
