Upper side band / Lower side band and persistence

I noticed something last night when switching from lower to upper side band while trying to find a couple of stations that I think were using USB on 40 meters. I had NR on while on LSB and when I switched to USB it was not on. When I switched back to LSB it was off also. So I turned it back on and set it to level 5 and then switched back to USB, turned it on and set it to level 5. Switched back and forth and it was off again. 

Is this a problem with persistence or is it normal ?

    This is where I get confused between profiles and persistence. It clearly shows in the Persistence table that WNB, NR, ANF, APF states and levels are remembered. Later, under global profile fields it shows each of these settings are controlled here also.

    Maybe it is true, maybe a doc issue. It is acting like a document issue.

    I created two global profiles. One for LSB NR5 and one for USB NR10. Switching between the global profiles keeps the NR settings. But as soon as I select the opposite sideband manually NR goes away. 

    This seems to happen for NB, NR and ANF but not WB.

    This is neither a persistence or profile issue.  Persistence is primarily band related, meaning you change from band A to band B and your radios remembers the previous band operating state (number of slices and their configuration.  Persistence is also recalled when you restart SmartSDR and connect to the radio. 

    Profiles are a snapshot of the radio's operational state that can easily be recalled.

    When you change modes on a slice, neither persistence nor profiles paly any part.  The former because there wasn't a band change and the later because you did not invoke a profile.

    When modes are changed, noise mitigation is turned off because these are transient controls that most liekly need to be reset after the change.
