I do get some validation warnings. "Validation warning. XLS to Raw Table: Data Conversion: The component has inconsistent metadata"

The only thing I can think is that in my data conversion I mapped for up to 60 columns. None of the Excel files will have this many (so they tell me). Some of the columns also have NULL as the value in the first row. These NULL columns seem to be the numbered errors.

Did I miss something in my conversion step? When I look at the Excel Source, I am able to preview the data set correctly, but those NULL values are in there.

Thanks so much for the assistance!
