the only way to fix it is to test and help here which is what im trying to do. there doesn't seem to be any good active forums about the editor all my posts get ignored for in game things.
The Act part is indeed the enemy level. and the reason it shows ??? is because its to high for you to know because your character is 4 or more levels below it i believe? So once you level up it will show the level, i think i have a way to show it no matter what but still testing.
And maybe the reason your having the not applied issues is the same reason i was. once you change something in your mod and re-save and publish it DONT load the save that actually had the old mod in it, i reloaded a save that never had any mods and all my changes in the editor applied in game as well. I just keep a save right outside the teleport to my level to check my changes.
