To my knowledge the Xbox One will reserve space to be used for the save files for each game you play. You should be able to see the amount of reserved space it has set aside if you select Mass Effect Andromeda and hit the menu button on the controller. Go to Manage Game, then select Saved Data. You should see all your local save files there, along with a block for the reserved space. That will show you how much has been allocated for that particular game.
If you haven't already, I would try clearing out that reserved space to see if it helps. When you start the game up again it will recreate the reserved space, so if something is amiss with the space that's been set aside already that might help.
