Getting Unable to format 2021-02-26 using format string yyyy-MM-dd

I'm getting Unable to format 2021-02-26 using format string yyyy-MM-dd  when trying to import a excel file.  I looked at my transform map and try to change the date format to yyyy-MM-dd it keeps reverting back to the default.

I have another date field that imports just fine with same date format.

[John Vo1]

so do i put in source script and reimport the excel spreadsheet?

There was a client script that prevented me from changing it.
