As Super Mario Bros.: The Lost Levels was considered frustratingly difficult by Nintendo of America, this had Nintendo needing to make a quick convert to an easier Super Mario Bros. 2. They then decided to reskin Doki Doki Panic into Super Mario Bros. 2 for oversea players, as they had already started developing Super Mario Bros. 3 at the time, but with a few changes to suit the American audience and the Mario series.
