Why is SOS / SOSEx misinterpreting the values ​​of System.Collections.Generic.List.Enumerator?

I wrote a simple C # application:

   static void Main(string[] args)
    {
       var list = new List<int> {500,400,300,200,100};
       var listEnumerator = list.GetEnumerator();
       listEnumerator.MoveNext();
    }  // <--- breakpoint here

I set a breakpoint at the end, launched it using Visual Studio, then activated windbg and bound it to the process (with the "non-invasive" checkbox enabled).

Then I entered the following commands:

.load C:\Program Files (x86)\Windows Kits\8.0\Debuggers\x86\sosex.dll
!mframe 17
!mdt listEnumerator

The result I got was clearly wrong (the fields are all messed up, it seems to report the value “index” under “current”, the value “current” in “version" and the value of version 'under "index". He received only one field on the right - the first one.

Local #0: (System.Collections.Generic.List`1+Enumerator) VALTYPE (MT=72dfd838, ADDR=0029efb8)
    list:02632464 (System.Collections.Generic.List`1[[System.Int32, mscorlib]])
    index:0x5 (System.Int32)
    version:0x1f4 (System.Int32)
    current:00000001 (T)

Then I tried to use SOS! DumpVC and got the same confusion:

    0:000> !DumpVC 72dfd838 0029efb8
Name:        System.Collections.Generic.List`1+Enumerator
MethodTable: 72dfd838

72e03aa4  4000c9a        8         System.Int32  1 instance        5 index
72e03aa4  4000c9b        c         System.Int32  1 instance      500 version
00000000  4000c9c        4                  VAR  0 instance 00000001 current

Why is this happening?
