For first one I don't know what you are referring to, is it "Payoff" or "Shower".
For the one next to the "Payoff" it's Chi scene (talk to Chi AI, Chi, Tell her about AI, talk to her again and after few days you get choice to upload Chi AI to HDD), and just wait couple of days.
But for the one next to "Shower" you need to archive true ending.
For second one you need to wait to night 13 I think and not fix Mia just talk to both her and AI, (I think it's like AI, AI, Mia, Mia, Mia) and when she tells you that she knows cascade time, you just wait till night 13 and they will solve it.
