Import/Export file excel with kendo

Question

I have a file excel (xlsx) created by Kendo (kendo.ooxml.Workbook) . In MS Excel, it show all columns. But when I try to read this file with ExcelReaderFactory, they recognize only 1 column. Does someone have this problem before ?

PS: If I make a minor change in this file (change cell's value) then save (the file's size increase 4kB). Now, I can read this file with ExcelReaderFactory.
