what is your timeline? did you resubmit all documents responding to your AOR2?
it is possible they have lost some of the pages during file transmission and scanning.
nothing to worry just follow the instruction and provide them the documents asked for, although there will be slight delay.
the 2nd one looks like they are asking for settlement planning. this is normal
the 1st one they probably need a marriage certificate that is notarized by PRC notary, if you get married outside of China you need to obtain a notary from local Chinese embassy.

For the AOC2 we didn't submit any of the "If not yet submitted" documents, because we already submitted them. We did resubmit
Updated Schedule A Background/Declaration form (IMM 5669)
Updated Additional Family Information form (IMM 5406)
For the settlement plan, I've actually already moved back to Canada since October 24th and my wife is here also on a visitor visa. Should I update the address in ecas to my Canadian address, or would it be risky? Technically she is here under dual intent.
