In a deal. Kan ban view. 

I see some green icons on some deals (right). 

And on some deals i dont see them (left). 

Both deals have open activities. 

Both of them have tasks as open activities. 

I tried refreshing browser. 

Creating the task on the deal view kan ban + in the deal itself. 

Seing tasks directly on the kan ban view helps a lot so i'm wondering what i'm not doing properly or signaling this bug.
