Month in cross table does not match date field

Month in cross table does not match date field

                              

I am having an issue in matching periods/months that head a crosstable to dates in a text file. Attached are examples of my data files, the output [actual generated versus what I need] and the QV document.
I have tried to change the headings to actual month names, did not work.
I go for easy solutions. So if the headings of the crosstable need to be changed, that can be done.

Who can help me?

thanks
