Using R script in the query editor doesn't like row headers

Hi Power BI Community

 

We are using Power BI and want to also use R script in our queries.  We tried using the "Using R in Power Query Editor" example here  https://docs.microsoft.com/en-us/power-bi/desktop-r-in-query-editor  that contains a very simple csv file for the datasource and example r script to run. What we are finding is that when we follow the example through we get the error below. Trying to debug this we have found that if we change the header names in the file to "a", "b" and "c" then the R script supplied in the example works finew with the new single value no space column headers. Is there a reason why we are having issues with the headers in R script? We are running PowerBi version 2.68.5432.841 (April 2019) with R version 3.5.2. We also tried upgrading the r version on another machine (again debugging as we thought it might be a machine issue) to 3.6.0 and get the same error. 

 

Any help would be greatly appreciated.
