I shut down the entire Xbox for 10 minutes and started it up again. I uninstalled and reinstalled the entire game plus all my DLCs.
I get an 'Insufficient Space to save your progress.' I assume that marked this Load as Modded which was fine until I went to save the game. It changed my Save data to '(M) Commonwealth instead of without the M. Added some Addon & Mod content for fun which created a new Save. Turned my Xbox on and did the Xbox update since it's been months since I've played. I haven't played my FO4 game on Xbox One in a bit.
