Yeah, those symbols are the variables. If you see them it's because it hasn't imported your choices. Here's a step by step to make it clearer!
1. Once you reach the last page of Act 1, you get this button that you have to press to save your choices.
2. This file will automatically be downloaded.
3. Now, in Act 2, select to import your choices from Act 1. (It only works on PC)
4. Now press the button that says Import Saved Data.
5. You'll get this pop-up message that says the import has been successful.
6. Now press Continue.
7. And your choices from Act 1 are loaded.
Hope this helps!
