Alteryx to Tableau Server using Publish to Tableau

[aetingu33]

Dear all,

Initially I published my tableau dashboard to the server using the Tableau Desktop application and did not embed the datasource.  What I want to do now is to update this data source using Alteryx.  I can update it, but the workflow does not show anything once it's data is refreshed.  I made sure the column names were the same, but when the data is set to overwrite the existing data source, everything disappears.  Even though I can see the correct fields there but duplicated.  Where am I going wrong?

Any help is appreaciated.
