HW Inventory trouble

Question

The following is with SCCM 2012R2 CU3
I have been adding a few Hardware Inventory classifications. 
Mostly, they work correctly but sometimes they don’t work quite right.
Usually, the inventory shows up in Resource Explorer correctly, but other times it has an unexpected category listed, and does not contain data.
For instance…  I imported the mof below, and instead of the category showing in Resource Explorer-Hardware as “Warranty Information,” it shows as “SMS_G_System_Microsoft_Warranty_Info_1_0” --- the WQL name instead of the SMS Group Name…
weird. 
The tables and views in the SMS database are named as expected “dbo.WARRANTY_INFO_DATA” and “dbo. v_GS_WARRANTY_INFO” along with the correct history tables and views. 
Also, those tables and views are filling correctly with data sent from clients. 
The data is NOT displayed correctly (no data present) in the Resource Explorer for hardware inside the console.
If I remove the hardware inventory class, the tables and views are deleted correctly  and the misnamed “SMS_G_System_Microsoft_Warranty_Info_1_0” is also deleted from the Resource Explorer-Hardware in the console.
I have tried deleting it and adding back a few times – sometimes waiting over night before re-adding it, and the result is always the same. 
I also tried using the wizard to Add... the class instead of Import...ing it with the MOF shown below-same result. 
I have tried adding five other classes via MOF import and four worked correctly and one more had the same problem as this “Warranty Info” 
  Anyone have ideas?
[ SMS_Report (TRUE),
SMS_Group_Name ("Warranty Information"),
SMS_Class_ID ("MICROSOFT|WARRANTY_INFO|1.0"),
Namespace ("\\\\\\\\.\\\\root\\\\cimv2") ]
class Warranty_Info : SMS_Class_Template
[ SMS_Report (TRUE), key ]
String Description;
[ SMS_Report (TRUE) ]
String DateScriptRan;
[ SMS_Report (TRUE) ]
UInt32 DaysLeft;
[ SMS_Report (TRUE) ]
String DellIBU;
[ SMS_Report (TRUE) ]
String EndDate;
[ SMS_Report (TRUE) ]
String provider;
[ SMS_Report (TRUE) ]
String ServiceTag;
[ SMS_Report (TRUE) ]
String ShipDate;
[ SMS_Report (TRUE) ]
String StartDate;
[ SMS_Report (TRUE) ]
String SystemType;
[ SMS_Report (TRUE) ]
String WarrantyExtension;

Here's what I would do--not sure if it would work or not, but it "can't hurt" to try.
Change that .mof import; modify this:
  SMS_Class_ID ("WARRANTY_INFO"),
Basically, get rid of the Microsoft| and |1.0 stuff in class_id.  I found--this was way back when cm12 was beta; that with that versioning stuff in classid I got goofiness.  Can I define "goofiness" no, not really.  I just know I'm
happier without that stuff when I'm importing custom .mof 's
