Can not delete a saved slot/journey in star wars jedi fallen order on xbox

Should there not be an option in the game's main menu to delete your save slot, you'll have to do it manually through your console's storage/through the game's storage settings. This may erase all progress made on the came, so be cautious about it.

The most probable way to do this would be by deleting your cloud saves for the game. https://beta.support.xbox.com/help/games-apps/game-setup-and-play/cloud-game-saves-faq
