Virtuoso is not importing wire-patches/rectangles defined in DEF 5.8 file

Hello Cadence Friends/Experts,

I am facing an unexpected problem where something defined as specified in the LEF/DEF 5.8 Language Reference documentation, doesn't import into Virtuoso (version IC6.1.6-64b-500.11) properly.  Hopefully, I have included all the pertinent information so that one of you might be able to reproduce this problem and help me understand how to fix the problem.

I am using Encounter to route my traces for a large cell and then exporting the output of that Encounter layout as a DEF file.  Encounter creates wire-patches in order to fill in notches that would normally not meet the minimum spacing requirements.  These wire-patches aren't being imported into Virtuoso despite being specified in the DEF file, as rectangles according to the LEF/DEF 5.8 Language Reference. 

I have created a dummy test DEF file to test exactly what is written in the language reference, in Example 4-12.  I have included a screenshot of this portion of the PDF for your convenience below.

I have implemented this basic routing net as specified in my DEF File below (with scaled dimensions), with the hope of creating a rectangle in Virtuoso:

When I import this file into Virtuoso, I get the following routing, which doesn't include the rectangle defined by RECT ( -3000 0 -1000 2000), which is contrary to the info in the LEF/DEF Language Reference.  As you can see, it only routes the wires from (0,0) to (5000,0) and (7000,1000) to (7000,7000).  For reference, the green square is a 10um x10um bounding box.  The units in the LEF file are in units of nm, hence the 1000 to represent 1um.

Any ideas about why drawing wire-patches/rectangles isn't working for importing DEF 5.8 into Virtuoso?
