Let me help you show your charges in the Expenses section.
Most of the time, categories don't' show on the Expenses if not filtered correctly. With that in mind, let's search the account in the Expenses tab and specify the Category tab. Here's how:
From the left navigation, choose Expenses.
Click the Filter tab.
In the Status, select All statuses. The Delivery method is Any. Specify the Date you split the transaction. Payee is All. In the Category select the expense account where the charges are located.
Once done, click Apply.
If the charges still don't show, I recommend reviewing the split transaction to ensure it falls into the exact category so that it will show in the Expense tab.
