Dynamic Data Source Not Working

[clowpow76]

I'm using a Dynamic Data Source for a Pivot Table, and for some reason it isn't caputing all of my data....it is only capturing 1431 rows of data and I have 1495. Formula I'm using is =OFFSET('Store Delivery Issues'!$A$1,0,0,COUNTA('Store Delivery Issues'!$A:$A),13)

What would cause it to not capture my last 64 rows of data? Cells are formatted exactly the same?

Problem solved, thank you. I had a group of blank cells in column A.
