It may happen that, after some time you have measured a profile, you need to change its target gamut for reporting.
I see two options: either changing it from "Reporting" or modifying and saving it from "Manage".
In this last case, you have to keep in mind that, the info I squared here below is not retrieved from the original profile, despite it available in its bcs file), but from the latest saved profile.

Only the Green items are loaded from the profile metadata when a Report is generated.
And that all works as expected, so I don't understand what you are trying to say?
I see no issue
