How do I get SolidWorks to automatically disregard non-existent/really small "interferences"?

In my assembly with 8020 extrusion and brackets, the "Interference Detection" feature is finding interference where there is none, and in my large assemblies it's making it difficult to search through and find the actual interferences. In this example assembly, I have a bracket and a bar with a coincident mate between the bottom of the bracket and the top face of the bar. With the measuring tool with precision set to 8 decimal places, it's clear that the angle bracket and bar are perfectly flat and cannot intersect, but the Interference Detection tool tells me that there is 0.00017mm^3 of interference as shown.
