Hi community,
Recently, I'm trying to make a plan focus on resource management/planning.
I have created 3 teams in Plan which are all Kanban team, estimated by days.
And I assign stories to these teams with original estimates values.
In the capacity view, I can see that some of the stories allocated days based on the team capacity and others are not.
In below example, my story has original estimates as 15 days and team capacity is 10 days per week. So, it allocates 10 days for the first week and 5 days for the following week.

Another story has original estimates 20 days and team capacity is 10 days per week. It allocates 5 days in the first 2 weeks and 10 days in the 3rd week. 
I don't know what is the reason behind this. Please help me on this. Thank you!
