@suman1083: the real answer to that is that dragonball canon doesn't matter and really just recommend people watch/read what they want. toriyama changes his mind a lot. toei came up with non-canon ideas (bardock , broly , history of trunks) that toriyama years later made canon.but yeah Dragonball Super takes place about a yearish? after the defeat of Buu. So it renders these last 2 episodes of kai (and the corresponding chapters of the manga) "non-canon".Big media franchises get retcons all the time. So it's whatever.
