Change dates based on other visual

Hi there,

Struggling to solve this one...

I have two data sets.

- Resource capacity in days

- Resource-demand in days

My source data sets have dates across the columns so I unpivoted these columns, then used a DAX formula to format these to Month and Year (then had to add a date sorter column YYYYMM)

Visual 1 - Shows overall demand by month

Visual 2 - I want to show demand vs Capacity. and have this change when the month is selected in Visual 1

But... only the demand changed, not the capacity. its always stuck on overall demand 

This is the relationship currently. I have tried making other relationships but doesn't solve this

Do I need a bridge table to solve this?
