OK, after doing some more experimentation and reading more about the presets, this is what I have figured out.
I found .Why are all settings in "Quality" & "Material" very helpful in this regard.
I now understand the color coding of the presets. If you look through the menus, the items in the settings show the colors of the preset that changes them from the base layer and these things change with the presets. The problem I had was if a user changed an item that is not a changed item in the preset ( such as Settings/Filament/Retraction/Extra Length on Restart ), then that item shows up in blue in the menu. It is invisible if not in Advanced mode and it is not changed if you call up a preset that does not have that item changed. It does not change even if you call up the default preset. It also does not change if you import a preset unless that setting is modified in the preset you call up. The answer seems to be clicking on Profile.../Reset to Defaults before calling up a preset. That seems to clear all the blue user changed items. I can work with that.
I am still a little confused about automatic syncing though. I think this may be causing some problems also. I think I will open a new topic for this.
Thank you for your assistance.
