with stock code entity.grid.xml.config calls <xsl:value-of select="aspdnsf:PagingControl($BaseURL, $CurrentPage, /root/Products2/Product/pages)" disable-output-escaping="yes" /> and and /root/Products2/Product/pages comes the excution of aspdnsf_GetProducts.
Which leaves two possiblites:
1. That that StatsFirst is set to 1 in the xmlpackage
2. aspdnsf_GetProducts is having trouble returing page stats results
Hope that helps to point you in the right direction.
