I would like to register a complaint, which is also my case, that I am unable to complete Audrey and Louise's internal conflict missions, nor Rose's final romance mission. Has the mission where the characters are Olivia's models been completed yet? It hasn't appeared for me, only the mission to recruit the models. And of course, I have scenes from the gallery that appear as locked and haven't appeared in the game yet. I thought that if a scene was locked, it meant it was already in the current version...
The hearts and conflicts only display missions that already exist in the game. At this point, none of the characters have a fully completed romance arc yet. As for the locked scenes — most likely one of the missions didn't trigger for you. In your screenshot above, there are two scenes left from Audrey's personal conflict finale. Try visiting Lillian in the evening and checking if she has a quest. At some point, the story progression was tied to her quest.
