Hi,
I'm exploring how Time and material projects work and the options they offer and I'm a bit confused when it comes to charge fees. I'm exploring the functionality as a way of journalizing markup.
As I see it there are two ways of doing this:
1. Through a fee journal - create the fee transactioins and then select them on the invoice proposal. This works fine, it creates fees lines.
2. From the invoice proposal - there's an option called "create fees" (see screenshot) but I can't make it work.

Anyone knows how to make this work?
