Unable to Access IEXPLORE instance in Name Mapping

I'm having trouble accessing an IEXPLORE instance in the name mapping editor. I have about 6 IEXPLORE instances that are mapped. They are all mapped using two properties ProcessName and Index. All ProcessNames and Index are the same. I added more properties (child count and FileVersionInfo) to one of the instances (IEXPLORE2) hoping that Testcomplete would select that instance over the others. Now the tests won't recognize it and to make matters worse I can't remove the extra properties because the object doesn't "appear." I get the 'Unable to edit the object because it doesn't exists' error message when I try to edit the instance.  How can I remove the ChildCount and FileVersionInfo properties?



Also, how does testcomplete select an instance of IEXPLORE if there are multiple instances and they all have the same identifying properties and values?
