Year 2017 does not exist in acme site for Reframework assignment 2

Hello. I am working on ReFramework Assignment 2 (Generate Yearly Report)
I am asked to download and merge monthly reports for year 2017 for each WI4 type item. However currently 2017 is not an option in acme website. There are only 2019 and 2020. Which year I am supposed to consider? And what should be the name of my upload file? should I stick on 2017 or should i replacethe year in file name with something else?

From the assignment walkthrough it specifically stated that the year you should use is the previous year so 2020 - 1 = 2019, unless the walkthrough changed?
