Pivot showing null for month year column

[Newbie777]

Hello,

I created sales pivot table by customers with month year data, and although there are all the date fields with no null data, I have a column showing empty data, while other columns show proper month year figures.  I'd appreciate it if someone could let me know how to fix this.

OK. I just solved it by unticking "Include null values" tickbox.
