Good to know this is a common issue and not my fault.
I found some other stuff that I am unable to override within the stats editor:
1. Within the Stats/Character tab changing the Accuracy entry of _Base doesn't effect the game
2. Within the Stats/Character changing the perseverance entry of CasualNPC, NormalNPC and HardcoreNPC doesn't effect the game
Not being able to override stuff stops my progress on so many fronts
