build Relationship Problem

Dear Team,

I have three different data-sheet in Power Bi and trying to build a relationship based on the date dimension table but facing the below error.
scenario
When I use each table wk# to create a visual in PBI, the data spread is correct for each data sheet week on week basis.
However, when I create many to many relationships (suggested by Power query automatically and without any other option), the table visual or line chart shows the total quantity only each week instead of each week's quantity. Kindly see below some sample data tables.
