Well heres the deal with that.
A lot of times when filming musicals, the actors sing live with their prerecorded track. Megan Hilty is quoted saying that she always sang "live" on Smash rather than just lip synching because the "live" singing makes it look more real to the audience. And I think that's what they did with this. It should all feel live.
Now, they could've sung some songs live, particularly the emotionally driven songs to provide the actors room to do things with their voice and emotions, that were not done in the studio.
I know that in Mammia Mia they mixed Meryls "live" singing with the prerecorded singing during "The Winner Takes it All".
Songs that I see them doing this with (mixed or entirely live):
The "discussion singing" like, "The Spell is on Our House"
Stay with Me (Meryl will probably do some things with her voice to add to the emotion of the song)
No One Is Alone
Moments in the Woods
