The simplified process was introduced last year and it is applicable only if you are sending your PR application outside buffalo. For example, a Nepali citizen can apply from New Delhi under the simplified process and as a regular process in Buffalo. Only condition to apply in buffalo is you have lived in Canada or USA for at least one year prior to your application.
If you are submitting your application in buffalo, you are under the regular process. That means you have to submit all the documents at the first time of application.

Aba ta ghaito ma gham lage jasto bhayo hola ni.
