DXF Map file - being changed automatically by SW

We have noticed an issue recently, but we're not sure if it's a 2010 issue or not.  We use a map file when we export our DXF files, that way the part geometry is on the correct layer for our lasers.  The map file is for profile, bend lines, sketches, and text.  The contents of our map file are this:

[Version]
SW990001

[Layers]
0 = 7, 0
DEFPOINTS = 7, 0
BENDING = 4, 2
CENTER = 2, 7
DIM = 3, 6
ETCH = 1, 1
GRAIN = 240, 6
HIDDEN = 5, 2
OPEN = 6, 1
PUNCH = 3, 1
SCRIB = 2, 1
ROTATE = 240, 1
SSINFO_FRZ = 7, 1
TBINFO = 6, 1
PROFILE = 40, 1

[Entities]
Geometry [0] = BYLAYER, BYLAYER, PROFILE
Center Lines [14] = BYLAYER, BYLAYER, BENDING
Notes [2] = BYLAYER, BYLAYER, ETCH
Sketch Lines [16] = BYLAYER, BYLAYER, PROFILE

[Colors]

Normally when we export a drawing to DXF, this is what the dialog box looks like.  It shows all 4 of our export items in the center column.

Now for the problem.  If I create a sheet metal part that is a plain rectangle (no bends) like Part 3 attached, then right-click on the flatpattern and export to DXF from the part, this is what the pop-up box looks like.  The center column only shows the profile, it does not show the bending, sketch, or text items, like the drawing did.

If I open my map file after exporting this part, this is what it looks like:

[Version]
SW990001

[Layers]
0 = 7, 0
DEFPOINTS = 7, 0
BENDING = 4, 2
CENTER = 2, 7
DIM = 3, 6
ETCH = 1, 1
GRAIN = 240, 6
HIDDEN = 5, 2
OPEN = 6, 1
PUNCH = 3, 1
SCRIB = 2, 1
ROTATE = 240, 1
SSINFO_FRZ = 7, 1
TBINFO = 6, 1
PROFILE = 40, 1

[Entities]
Geometry [0] = BYLAYER, BYLAYER, PROFILE

[Colors]

The map file is actually being changed by SW!  It removed my items for sketches, text, and bend lines!  I believe this is a bug or something, SW shouldn't overwrite our map file automatically. I'm not sure if SW2009 did this, I don't believe that it did.

Can anyone else replicate this?  I plan to try it on some of the computers at SW World next week also.

Thanks,
