After cleaning the masters, the guide says
At this point, the Bethesda masters should be cleaned and the mod list order in the left pane should reflect (Note that the plugin order may be different):
Creation Club Mods...
DLC: HearthFires
DLC: Dragonborn
DLC: Dawnguard
Cleaned Vanilla Masters
xEdit Output
But my mods had the DLC first, then the CC mods, even though I followed the guide exactly.
