Both date was only once and data is still going on. The strange thing is that in the analysis section all correct and no issues.
On name column I cant use space and other feature so
you have violated most of the rules for naming fields
no spaces (use an _ )
don't use keywords (List may throw issues in some situations)
So rename the fields in excel. format them explicitly as to their data type and don't leave blank cells, provide a "null" value appropriate for the data type
