P: Profile corrections: Setup "Default" is saved as "Custom" in Default Develop Settings

[LRuser24]

Steps to reproduce:
1. Load a RAW file with known lens into develop module
2. Klick "Set Default..." and "Restore Adobe Default Settings"
3. Reset (the photo has now Adobe default settings, profile correction is not active)
4. Activate profile corrections
5. Set profile corrections setup type to "Default" (should already be set upon activation)
6. Klick "Set Default..." and "Update to Current Settings"
7. Reset
8. Also reset (or import) some other photos taken with the same camera
9. Look at the camera's Default_nnnnn.xmp file in Adobe\CameraRaw\Defaults

Expected results:
- After the second reset, the profile corrections setup type *remains* at "Default"
- Other photos are reset to / imported with profile corrections setup type "Default"
- Default_nnnnn.xmp contains crs:LensProfileSetup="LensDefaults"

Actual results:
- After the second reset, the profile corrections setup type *changes* to "Custom"
- Other photos are reset to / imported with profile corrections setup type "Custom"
- Default_nnnnn.xmp contains crs:LensProfileSetup="Custom" and all other explicit settings including make, model and profile.

The bad thing is that other photos for the same camera but *different* lens get the wrong correction for the custom lens profile stored in step 6, i.e. the *wrong* lens! This happens at reset and at import.

Workaround: Replace Step 6 (Klick "Set Default..." and "Update to Current Settings") with:
6.a: Klick "Set Default..." and "Update to Current Settings"
6.b: Reset: Setup wrongly changes to "Custom"
6.c: Change setup to "Default" again
6.d: Klick "Set Default..." and "Update to Current Settings" again
Using this workaround, the default development settings are saved correctly with profile correction setup type "Default".

Edit: Simpler Workaround: Replace step 5 (Set profile corrections setup type to "Default") with:
5.a: Set profile corrections setup type to "Custom"
5.b: Set profile corrections setup type back to "Default"
This seems to do the trick, too. Something must be out of sync between what is displayed in the GUI and what is internally stored in the development module data structures. Changing the setup type back and forth seems to bring both in sync again.

Additional remark: This bug only affects the default development settings. It does not affect the creation or update of user development presets.

System: Lightroom 3.6 final on Windows XP prof. SP3 (32 Bit), no LR plugins installed.

This seems to be fixed in LR4Beta.
