Dasymetric Tool: Dasy Output Excludes Some Blocks

I have been working with the Dasymetric Mapping 2014 tool for ArcGIS 10.2.2. I applied the following to the tool:


-Population: US Census Block 2010, for a region of CT

-Land Use: NLCD 2011, clipped to CT and Reclassified to 1-High, 2-Medium, 3-Low, 4-Uninhabited

-Key Field: OBJECTID

-Population: POP10

-Uninhabited: 4

-Coverage: 80% (Default)


A closer look at the "dasy_rast" saw some areas where entire blocks contained 0 NEWPOP/NEWDENSITY cells even with a positive population and inhabited classes. Anyone else run into this problem? Any thoughts as to why this might be happening are appreciated.
