Odd. I'm on Sun of Week 10 myself, and I completed all storylines. Walk me through what you've been doing with Ms. Ana specifically (what time of day you try to visit, what choices you make during visits, etc.). Maybe there's a step that's being missed somewhere.
For Liza, it seems like a lot of people get a little confused at different points. You may want to look over my post here to see if it helps:

Like I asked for Ms. Ana, walk me through what you're doing with Lucy, the order in which you're doing it, what choices in each of the events you're making, etc. It's very possible some small thing is being missed.
