Don't dwell on what YG says about the lineup since a lot can change before the debut. Some people get cut, while others can go and get added back in. It's pretty much the reality of pre-debut life.
Also, I wouldn't dwell so much on fantaken pictures. They're only a snapshot of a single day, and seeing anyone's faves often relies on luck. A lot of people who go there aren't always interested in other YG acts either. No need to make mountains out of molehills. It's just unnecessary stress.
