It's stated in my Code of Conduct, but the majority of the paid DLC cannot be used in YouTube videos because it's paid content and shouldn't be shared for free.
I also don't have an official guide, as the DLC is still a massive work in progress. All I can suggest is making different choices to unlock new paths and always picking the choices with the flame icon :3 For example, some additional scenes depend on whether you stay at Ren's or Angel's home.
I don't really understand what the problem is ^^; Unless you're absolutely certain you've installed the DLC correctly and you've started a new game, there shouldn't be any issues. You'll get the flame icons naturally as the game progresses from the beginning.
If possible, please show a screenshot of the DLC inside your "game" folder — that way, I'll be able to see whether you've installed it correctly or not :3
