Rental income classified as non passive so I don't get the $25,000 deduction

I have several  "passive" rental properties on my taxes with income.  Turbo Tax identified the income for only 2 properties as NPA non passive income and reduced my $25,000 deduction.  I checked my answers to make sure they were identified as passive with active participation.  What could be the reason for this?  The 2 properties are land.
