Since RPG Maker MZ release, You can use same size tileset from MV for use MZ but one thing only Tileset B maybe problem in first spot I don't know why.
But don't worry about other section tileset because all working except Tileset B only.
So you don't worry :) I think some dev need to manual arrange them before use on own games
I tested on RPG Maker MZ Ver.1.5.0
