yes I arrived as visitor in april 2016, extension approved, then I became PR in sept 2017.
it sounds I arrived to nowhere. I lost the opportunity to live in France.
My application was returned. According to IRCC:
"In your particular circumstance, some or all of the time reported on the Physical Presence Calculator (prior to the Permanent Resident date) could not be confirmed in our records."
What next to me?
1- what kind of TVR? visitor?
go to India and send your passport at your local Indian VAC.
good luck
just in case

don't worry about your sister
if your sister were really interested is her problem, she would fine some help by herself, at least that she does not meet the Residency Obligation.
you have nothing to do, it is her business
