Activity expenses do not show up in budget detail

Dear All,I am learning how to use finance module. I have created budget items and expenses. When I check the budget amount everything is perfectly correct.However, when I check the 'Detail' tab in 'Budget' item, only project expenses show up. No activity expense is shown in Detail tab but the number show on the tab seem correct.

My question is, is this the correct behavior? If so, is it possible to config Projeqtor to see every expense, including project and activity expenses, on the budget Detail tab?

Thanks
