The 44th Filmfare Awards were held on February 21, 1999, in Mumbai India. Karan Johar's directorial debut "Kuch Kuch Hota Hai" dominated the awards, including a sweep of the major acting categories. Ram Gopal Varma's "Satya and Mani Ratnam's "Dil Se.." were the other big winners.
Ram Gopal Varma's "Satya" won an award for best actor.
The context mentions that "Kuch Kuch Hota Hai" swept the major acting categories. Best actor would be considered a major acting category and a sweep means that the film won every single category mentioned. As such, "Satya" could not have had a best actor winner that year. The system possibly got confused by the context of sweep in an awards ceremony.
