Pulling a List of Individuals Not Part of a Household

We are trying to pull a list of individuals not part of a household for some database clean-up, and even with the criteria Constituent Type-In-Individual and Constituent Type-Not In-Household we are still getting constituent results that are a part of a household. 

Has anyone else encountered something like this before? Do we need to go into Manuel Entry and edit it there?

Any insight is appreciated!
