[Koha] change biblio. info. doesn't change normal view of the same record

Hi, I'm Abdullatef from Malaysia, I'm a new user of KOHA. I'm facing this problem right now: - when I change biblio. information of a catalogued record and save it, I can see the full changes in MARC view. Information in normal view (tag 100, 245 and several others) remains. - anybody have solution?
