Description
In the process of selecting neighboring points for a location, the values for Maximum neighbors and Minimum neighbors refer to the number of neighbors to be included for each of the sectors (1, 4, or 8) in the neighborhood shape. If the number of features in a sector is less than the Minimum neighbors value, then features will be selected beyond the search radius until the Minimum neighbors value has been reached, or all the neighbors in the sector have been included. The Minimum neighbors parameter does not override the Maximum neighbors parameter; it is used to define a minimum of neighbors for each sector.

Solution
Make sure that the value for Minimum neighbors is less than or equal to the value for Maximum neighbors.
