How do I generate beam reinforcement so that I only have hooks at the extreme supports and not at intermediate supports?

I realize that I can go to the reinforcement menu and modify bar shapes, stirrup spacing etc. However I am having trouble understanding the required and provided reinforcement over the support. See attached picture and figure marked in red. I have 3 x 20mm bars over the support so I was expecting an area of 9.42 sq.cm. instead of 3.25 displayed. I thought it could have something to do with the anchorage length but changing the length of the hook seems to have no effect.
As far as I can see you have frozen the reinforcement preventing Robot from changing it during the design process. I think the best way of understanding the situation is to look at the diagrams of bending moment along the beam vs. beam capacity (there you can see the decrease of capacity along the anchorage length of rebars) as well as required and provided reinforcement.

Even with "unfrozen" reinforcement, I am having problems changing the hook length. It has worked before so I must subsequently have set some parameter which is preventing it from doing so. Anty ideas what that might be?
Make sure you switched on the option indicated on the attached picture. Otherwise I need the file to look at.

Artur, please find file attached. Noticed the right end hook ican be modiified, but not the left.
Change the length of the hooks using the bar properties dialog.
