1) Display a profile
2) Change its Target Gamut (i.e. the one used with the measurements) with another one .... Better if very different
3) Close it
4) Display it again (without exiting from CS): The Target Gamut appears being the same as at step 1 (that's correct, as the profile has not been modified), but indeed its displayed data indicates CS is using the one used at step 2
No issue If at step 4 I close and open again CS.

Here my relevant screenshots:

Step 1

Step 2

Step 4

Good catch!
That's very good feedback.
