Incorrect skill being leveled for subjects under Computer Science Degree

I am not sure if this is a bug, but I find it peculiar that a Computer Science Degree Program's subjects: a. Auditing Artificial Intelligence and b. Applied Network Security both level up the Mischief skill. Is this correct or a bug? To my mind, this should be Programming or Logic. skill related. My sim already maxed out the Programming skill, is that the reason why?
