Sum of credit and debit in category report

Hi,

I'm using homebank to manage my bank account.
I'm using a category for example "health". In this category i've got debits (medecine) and credits (insurance). But when i display the sum up of the last month it sum only debits and not credits.

For example :

Debit 100$
Credit 90$

Real expense 10$, but it displays 100$.

I would like that it shows credit+debit which is the reality on my account.

Do you think that it is possible ?

Thanks in advance,

Pack
