I've discovered that a factory preset still leaves my old custom settings, and that isn't a total reset/preset. I suggest viewing your settings to see if everything was reset, and if it isn't, power off and do another FP and check again. I have done several software changes and had some odd behavior in the first ones. I just assumed that the FP was iron clad.
It can't hurt to preset until you get an absolute clean sweep of all settings. Hope this helps.
