We are definitely working on fixing this issue through a Title Update, but this is a lengthy process and we cannot estimate when it will be available. If your game loaded without the decisions you made, please exit to the menu and confirm the correct slot loaded (it will be the highlighted one). If it did not, then using the workaround will allow you to regain the use of your other save slots.
If the highlighted save is yours, then please log out and back into your profile, and your save should be accessible again with your choices. If loading Episode 4 shows the wrong choices again, then it's possible your save file was overwritten.
