Problems with proportional symbology and point data!

Running ArcGIS 10.3 for Desktop, with an "Advanced" license type.


What I'm trying to do: I am trying to display point data via proportional symbols based on a Square Footage attribute.  The square footage value is missing for some data points, while for others the value is so small it's impossible to see on the map.  I am trying to get it so it will display all values proportionally, except for NULL values and values less than about 10 square feet, both of which I would like to be displayed with normal points.


How I'm Trying to Do it....:  I am setting the feature class' symbology to Proportional (Properties -> Symbology -> Quantities -> Proportional Symbols), with Value: WeedArea, Unit: Feet, and Data Represents: Area.  To get the points with small and/or null values for WeedArea to display as normal points instead of proportional symbols, I use the "Exclude..." option which is in that same Proportional Symbols settings page.


The Exclude option basically just opens a query builder.  I have "Show symbol for excluded data" selected on the "Legend" tab, and in the "Query" tab, I am using the expression WeedArea IS NULL OR WeedArea < 10.  Clicking the "Verify" button says everything is good to go.


The Problem:  It isn't working how I'd expect.

     -  If I use the above expression, it displays everything that matches the exclude query as normal point features (which is what I want).  However, it also then hides all the points that should be displayed by proportional symbols (i.e., everything that did NOT match the exclude query).  This is a problem!  Why is it doing this?????

     - If I instead just do a single conditional and don't have any "OR" statement (e.g., I type only "WeedArea IS NULL" or instead only "WeedArea < 10") then it works correctly - it displays the data as expected with proportional symbols for everything that doesn't match the Exclude statement, and normal point symbols for everything that DOES match the exclude statement.



I would REALLY appreciate any help with this.  Is this not possible with ArcMAP?  Is it a bug?  Is there something I'm doing wrong?
