Question bank won't let me choose several questions?

Hi!

I'm working with question banks and I have seen a film where I should be able to choose a certain amount of questions to draw from - however that choice does not exist in my question bank - where can I find it? (I'm referring to the "number of questions and the roll down menu from this film: ELH: Question Bank examples). 

And one more question, on a different subject. Can i somehow choose that my links won't change color according to the theme color? I need to have a certain color for my company but when it is on the link text it becomes almost unreadable.
