When I select "All Transactions" and then click on "Spending" to see the combo pie chart/transaction information, I cannot filter on the parent category transactions by clicking that portion of the pie chart or the transaction total. For example, if I have a category of Children with 3 sub categories (Children:A, Children:B and Children:C). If I click on A, B or C is see just those transactions. However, if I click on Children, nothing changes. And, importantly, there are transactions for just Children. Is this a feature, bug or am I missing something?
