Issue adding 53rd week

Hi,

There is a requirement from business to add 53rd week for the year 2017 in a RPAS solution having calendar hierarchy from 2013-2018. I loaded a new file with -forceInputRollups parameter so that the dates are rolled up to correct week based on this change. While this change is correctly reflecting in the calendar hierarchy, when I am selecting the base intersection of a wb as week, the 53rd week of 2016 goes and sits at the last i.e. after 201852 week. If I select any other intersection, it sits correctly after 201652.

How can this be rectified? Is this related to the index number of the week? If so how do we reassign the index numbers for the weeks?
