EDIT: Well reading your last post, it seems I cannot file the thread yet... Why did you do that?

If you do want to go back to vanilla leveling after using a leveling mod, you will need to reset this internal count. This can be done after deactivating the leveling mod at the console by doing;SetDebugText 10ToggleDebugTextSetGameSetting iLevelUpSkillCount, <-nnnn>AdvancePCLevelSetGameSetting iLevelUpSkillCount, 10Player.SetLevelWhere <-nnnn> is the big negative number shown by the debugging text on the line "Major Skills Advanced: <-nnnn> / ", and is the level your character was at before doing this. After doing this the debugging text should show "Major Skills Advanced: 0 / 10". At this point you can save your game and continue using vanilla leveling.
